The quantitative and qualitative analyses document the evolution of this area from a marine environment dominated by relatively deep or circalittoral species at the base of the succession, passing progressively up into shallower environments, and at the top infralittoral coastal environments.
Particularly important from the ecological point of view is the presence in some samples of Bythocythere turgida. This species indicates deposition of these sediments during the cold phases of the Early Pleistocene. Comments on "Estimating the impact of early diagenesis on isotope records in shallow-marine carbonates: A case study from the Urgonian platform in western Swiss Jura" by A.
Godet et al. Although we agree with this conclusion we question their arguments and interpretations. These authors correctly identified diagenesis as the key factor, but we question the timing of events in their paragenetic sequence. In particular, they reported the leaching of originally calcitic oolitic cortices but failed to discuss this puzzling feature properly. In addition, the backbone of their argument is the stratigraphic correlation of a specific sequence from three dominantly shallow-water sections together with a basinal reference section.
However, a reliable alternative biostratigraphic framework shows that this attempt of long-distance correlation might be erroneous. It represents the oldest member of the Family Siderastraeidae. The genus is characterised by an astreoid arrangement, occasionally although some have a plocoid or a cerioid calicular arrangement, and a sub-regular hexameral, heptameral, octameral or decameral septal symmetry. The septal blades are made of medium-sized trabeculae.
Synapticulae are present. Almost a hundred specimens were examined, among them numerous type specimens. In total, 26 Cretaceous species were separated. Fifteen species were assigned to formally established species, three species were compared to one of these species, two species were described as new and the remaining six species were reported in open nomenclature. The genus occurs in the Cretaceous worldwide and ranges from the late Valanginian to the Santonian. It shows its greatest diversity in the earliest Aptian and early to middle Cenomanian. Represented by a very limited number of specimens this new genus consists of two species: I.
The suprageneric position of the new genus is difficult to determine because of the poor preservation of its sutural elements and the incomplete state of the specimens. The genus is tentatively assigned to the Family Macroscaphitidae Hyatt , , pending the study of better preserved material. The work by Burckhardt was the first report of Aptian ammonoids in Mexico.
In addition, it represents the only record of Aptian ammonites known from Zacatecas State. The taxonomic review of the specimens allows for the recognition of Dufrenoyia sp. This ammonite assemblage is indicative of a stratigraphic range that spans the uppermost lower Aptian to the upper Aptian interval.
They are relatively small, irregular in outline, and preserved as goethite, limonite, siderite and hematite. Although it is difficult to identify the producer of these coprolites, they were most probably formed by some fish. The Fort Lancaster Formation is the uppermost Albian carbonate unit deposited on the shallow water Barremian-early Cenomanian Comanche shelf. The Fort Lancaster represents one long-term transgressive-regressive cycle capped by a regional unconformity overlain by lower Cenomanian deeper water Del Rio Shale.
The erect stalk-like molds are up to 1 m tall and about 6 cm in diameter. The ridge crests are dotted by paired ringed depressions with small central nodes; these negative impressions indicate the presence of oval rings with small depressions inside of each ring. The diameter of the stalk is the same at its base as at its top indicating that growth did not expand the organism but extended it upward.
These stalk-like organisms appear to be rooted on disconformable bedding surfaces that were exposed to the atmosphere. Carbon isotope data shows the classic negative shift below subaerial contacts. Subsequently sea level rose and muddy carbonate sediment buried the stalk. The absence of original wall material suggests that the wall was composed of readily decayed or dissolved material such as organic matter or aragonite. Stalk-like organisms of this size and shape are rare and potential types are cacti, plant reeds, Porifera, or Scleractinian Cnidaria.
As a consequence of a marine regression episode resulting in a significant increase of salinity and a partial emersion of seafloor these bivalves vanished. The next transgressive pulse caused a re-emergence of these bivalves. They were initially characterized by half-size shells than in the population living prior to the regression episode and, subsequently, during progressive transgression, their shells returned to normal size.
Our current study focuses on the analysis of fifteen sections distributed along to the northern and southern limits of the Guir Basin, between the Ben-Zireg to the East and the Meridja-Boukais axis to the West. The three formations constitute an overall transgressive megasequence built of a number of transgressive-regressive minor sequences. The opening of the deposits towards the North is confirmed by the organization of the lithostratigraphic units and by the Tethyan paleobiogeographic affinity of the echinoids and bivalves, and especially the occurrence of Neolobites vibrayeanus ammonite.
The preliminary results of our investigations in the Mount Lebanon region are presented here. Our revised bio- and holostratigraphic interpretations and the new age assignations lead us to emphasize the importance of the two hiatuses in the sedimentary record below and above the Salima, i. On the fossil alga Marinella lugeoni Pfender , , nom. Part 2. Revision of the Jesse Harlan Johnson Collection. Although Marinella lugeoni Pfender , , is not the senior synonym, it is proposed to ascribe it the status of a " nomen conservandum ". We also document small Marinella lumps found in Albian-Cenomanian strata of Brazil.
However, we document that they represent three discrete species. However, on the basis of their diagnostic criteria, the species Cordilites cretosus and Parachaetetes asvapatii should not be confused. More than specimens belonging to various species of these two genera were studied, with the aim of identifying the specific characteristics and the stratigraphical and paleogeographical distribution of the various species which compose them, as well as to propose a phylogeny for the group.
This study confirms the non-synonymy of Heminautilus saxbii Morris , and H. They show lateral and vertical changes in facies, including conglomerates, limestones and stromatolites. Layer thickness tends to increase gradually from East to West and also to the South of the study area. Because of fluctuations in the groundwater table, these carbonates have undergone periods of flooding and emersion, causing many pedogenic changes.
The nature of these changes was controlled by the height of emersion nodulisation, roots traces, pseudo-microkarst. These pedogenic changes in turn affected cementation during diagenesis alternations of phreatic cement , justifying the rock classification as palustrine limestone. This is the diagnostic feature of Lithothamnion crispatum , a cosmopolitan hapalidiacean with a wide depth range in modern oceans. The comparison of the microscopic anatomy of both the fossil and modern L.
Therefore, this species has a long stratigraphic distribution starting at least 20 My ago, without significant morphological changes in either reproductive or vegetative anatomy. A classic example is the deep offshore of the Lower Congo Basin where numerous fluid-venting structures are present above a Pliocene polygonal fault system. In this paper we present a detailed seismic analysis of a newly recognised system of Quaternary-aged Linear Chimneys and their intersection geometries with pre-existing Pliocene-aged polygonal faults PF.
This indicates that fluid in this case gas migrated vertically, cross-cutting polygonal faults as it ascended through the tier. This is a strong indicator that PFs did not provide viable migration pathways otherwise chimneys would terminate at the upper tip of the fault, which would be the most likely migration exit point. Only twice in the whole system of Linear Venting Systems did this occur.
A sub-set of chimneys stems from or above PF planes but these are restricted to either the lower footwall or from the apex area of hanging wall. At best they are evidence of fluids migrating up the lower part of polygonal faults and exiting deep within the tier, then migrating through most of the tier in their own vertical leakage vents.
A simple technique allowing the extraction of this information by means of the UAgraph program is discussed in the present paper. The technique consists in modifying a usual database of UAgraph by augmenting it with the restricted data concerning only the FOs or LOs of the taxa under consideration. The resulting data set combines the information on total ranges and those concerning the FOs and LOs only. Calculating the UAs of such a duplicated database produce a range chart in which we can read the maximal ranges of all the taxa and, in addition, the biochronological dispersion of the FOs and LOs.
This trend can be detected visually by the means of the UAs reproducibility chart, output of the UAgraph program. In a more general frame, the same holds true for species whose regional dispersion is related to specific conditions and when these conditions migrate in space with time e. The above discussion is strictly related to FOs and LOs that for a given section are definitive, however well constrained ephemeral appearances and disappearances can be easily integrated in the database for the same purposes.
All specimens of Hemidiadema from these regions cited or described in the literature until now were related to the species Hemidiadema rugosum Agassiz , Three new species are proposed and described: Hemidiadema batalleri nov. The species H. Remarks on the paleoecology and stratigraphic and geographic distributions of these species are given. Conichnus conicus also occurs in clay-rich carbonates of the early Silurian of Estonia. Lateral adjustment traces are more common in C.
The lack of adjustment traces in Amphorichnus , together with its morphology, does not support synonymy of Conichnus and Amphorichnus. The Conichnus conicus and Amphorichnus papillatus tracemakers preferred shallow water carbonate environments with high clay content. They were rare or did not occur in deeper water muddy environments or where shallow water carbonates accumulated.
A high content of volcanic ash in the depositional environment is characteristic of both the Ordovician and Silurian maxima of Conichnus conicus occurrence. In this paper, a detailed architectural study has been carried out on selected, agglutinated larger foraminifera, which include Choffatella aff. Moreover, it presents their biostratigraphic range and the range of the associated porcellaneous and lamellar-perforate foraminifera in the study area.
The assemblage is Early Campanian in age.
What is phishing?
Scientific death-knell against databases? Errors induced by database manipulations and its consequences Christian C. The page concerning T. The decrease of the specialists in systematics and their replacement by IT specialists question the scientific reliability of the online databases as well as the specimen labelling in museums. The absence of scientific rigour becomes their Achilles' heel. Several other cases of errors are quoted and developed. In spite of applications to the staff of databases in biodiversity, the situation continued degrading so much so that today these bases are reached by the Peter principle and can no longer be used for scientific requirements, except if verifying all the desired data.
The rich charophyte assemblage described by Grambast and Lorch from a site near Jezzine is Barremian possibly Early Barremian in age, not Bedoulian as previously stated. Besides gyrogonites and utricles, charophyte thalli are rather common; they are ascribed to two organ genera, Munieria Deecke , , and Charaxis Harris , Based on topotypic material from the Pia Collection , Munieria baconica Deecke , , the type-species of the genus, is reassessed. In addition, the species Clypeina parvula Carozzi , , is transferred to the revised genus Munieria , and a new species of Charaxis is described.
The ostracod fauna from nine samples is poorly diversified but well-preserved: A total of forty taxa of ostracods have been identified, thirty-three at specific level and seven at genus level or doubtful species. Thirty species are considered as constituents of the in situ original assemblages. The associations consist almost exclusively of bathyal taxa such as Bythocypris obtusata Sars , Anchistrocheles antemacella Maddocks , Henryhowella ex H.
Also the Krithe group is well-represented with Krithe compressa Seguenza and K. Almost all species, some, particularly interesting from the palaeoecological and palaeogeographical point of view, have been here described, illustrated and commented on, including a species belonging to the genus Cytherella Jones , , found in all samples of the section, which is here proposed as new. We also include images of these ammonoids since they were not illustrated in Astre 's original work.
This taxonomic review allows us to identify these lower Aptian ammonites as Pseudohaploceras liptoviense , Deshayesites sp. The thickness of the Cenomanian succession changes from around metres in the fully marine sections to metres in mostly continental facies in the western High-Atlas, about km updip, to a few tens of metres in the Bou Tazoult area. The strata thicken again eastwards into the Pre-African Trough where they can be traced without major facies changes to the Kem Kem embayment and to the Bechar area in Algeria.
Over all this eastern area, continental facies are overlain by the fully-marine shallow-water deposits of the Cenomanian-Turonian boundary interval. A first major conclusion is that fluvial aggradation in high-frequency transgressive-regressive sequences is coeval with the seaward-shift of the shoreline, in accordance with the genetic sequence stratigraphic model of Galloway Both the flatness of the depositional profile and the corresponding very low energy of the marine environment during the transgressions account for the blanket of red continental clays on top of marine facies in updip depositional sequences, which is then preserved under the marine transgressive surface of the next sequence.
A second major conclusion is that the high-frequency transgressive-regressive T-R sequences do not look like classical parasequences bounded by transgression surfaces. They usually exhibit a surface created by a sea-level fall within the regressive half-cycle. This is interpreted in the following way: regressions did not operate through a regular seaward-shift of the shoreline, but through stepped sea-level falls. The very low slope of the depositional ramp is thought to have enhanced the sequence stratigraphic record of such stepped regressions. Short-term, high-frequency sequences are organized into medium-frequency T-R sequences seven in the Cenomanian which show an overall aggrading and slowly retrograding pattern along the whole transect.
Comparisons with other basins show that medium-frequency sequences do not fit the third-order depositional sequences described elsewhere, casting doubts about a eustatic mechanism for their deposition. End of a modern geological myth: there are no rudists in Brazil! However, petrographic analyses demonstrate that these shells should be assigned to Ostreids or to Pycnodontids rather than to Rudistids.
In addition, the scarcity of corals leads us to ascribe the taphonomic assemblage to the Chloralgal facies. Neither generalized hypersalinity or extreme sea-water temperatures seem to account for these biotic peculiarities. Instead, our alternative hypothesis favors the driving role played by oceanic circulation in the dispersal of the benthic organisms. The petrographic study reveals a range of lithofacies from wackestone to packstone.
A large part of the material was collected by Prof. Charles Barrois and Dr. Other, poorly documented specimens were purchased from the enterprise Krantz towards the end of the 19 th century and in the first years of 20 th century. The geographic position and stratigraphy of outcrops, from which the material originates, are briefly discussed.
The latter is characterized by the disappearance of Olcostephanus drumensis and the appearance of Luppovella superba. The assemblages characterizing each of these biozones can be recognized throughout the Mediterranean region. They include echinoderm holdfasts i. The earliest hardground faunas appeared in the Dapingian i. The Estonian hardground faunas are less diverse than the North American ones. North American hardgrounds seem to be more heavily encrusted than the Estonian ones. These differences may be due to the paleogeographic distances, different climates and different sedimentation environments of the paleocontinents.
MayLib - a textfile-based bibliographic database for geosciences and a list of references on Devonian matters Andreas MAY. One solution for this need is MayLib, a bibliographic database that runs on many different operating systems and does not require pre-installation of any software. MayLib is a very small, efficient and comprehensive JAVA program that handles references to publications in any Unicode-compatible language.
It is user-friendly and not only contains the basic functions of a bibliographic database, but also has some advanced features. Using MayLib the author has been able to create a list of references, which contains periodicals and literature references. Of these references deal with Devonian matters and references deal with corals.
This study integrates data obtained from the analysis of ostracods, foraminifers, bryozoans and serpulids found within a six metre thick sedimentary section. This multiproxy approach allowed us to reconstruct the palaeoenvironmental evolution of this south-western sector of the Hyblean Plateau Comiso-Vittoria area from fluvially-influenced shallow marine settings, recorded in the lower portion of the succession, to progressively shallower, transitional and brackish environments, testified in mid levels, up to freshwater environments at the top of the section.
Belemnites sulcatus Miller has been variously equated with either Belemnites apiciconus Blainville or with the group of belemnites including Belemnites Altdorfensis Blainville and B. Beaumontianus Orbigny. Riegraf and not Phillips subsequently designated a lectotype which may be valid and, in case it is not, is validated here. The species concept for Belemnites sulcatus , as based on this lectotype, places it in the genus Holcobeloides Gustomesov. Belemnopsis Edwards has date priority over Belemnopsis Bayle , but must be interpreted as an "incorrect original spelling" and, therefore, does not enter into homonymy according to the ICZN; Belemnopsis Bayle is thus a valid genus.
One of Bayle 's figures of Belemnopsis sulcata agrees with Belemnites apiciconus Blainville , but does not agree with Belemnites sulcatus as defined by its lectotype; as such this is a case of misidentified type species. Belemnites apiciconus Blainville , the species involved in the misidentification, is therefore designated type species of Belemnopsis Bayle here and validated by citing the ICZN. The actions taken here maintain nomenclature at the genus, family and suborder level in respect to the names Belemnopsis and Belemnosis and serve to stabilize the complicated nomenclature issues related to these taxa.
This fauna bears out the palaeogeographic placement of Lebanon on the southern Mediterranean Tethys margin established by palaeostructural reconstructions. The associated micropaleontological elements suggest an earliest Aptian age early Bedoulian for the Offneria murgensis - O. These caprinid specimens are characterized by relatively modest sizes, moreover other rudists commonly part of the assemblage are lacking. The dominance of caprinids in the study area suggests a distal platform setting, i.
We present and briefly discuss a few types of proprietary and open-source, relational and non-relational, server-based versus portable databases and specific tools to handle the latter. This assemblage is analyzed from a paleoecological perspective. Such an assemblage yielding large ammonites is unusual in deposits of this age in Mexico.
To properly document this ammonite record, we review ' Gargasiceras ' adkinsi , formerly misidentified as Rhytidoplites robertsi , and allied taxa. From our analysis, we conclude that ' Gargasiceras ' adkinsi exhibits strong intraspecific variability. We also analyze in detail the differences that exist between ' Gargasiceras ' adkinsi and Rhytidoplites robertsi , and emend the concept of the genus Rhytidoplites.
These revisions are important from a biostratigraphic point of view since ' Gargasiceras ' adkinsi is an index species for the lower Aptian ammonite zonation of Mexico. The chief editor of a prestigious scientific journal, who is about to publish a major article of which Guy is one of the lead authors, replied to the news of his passing: " I am very sorry to hear about that.
I have known Guy Tronchetti from publications, for a long time. It is really sad. His great modesty did not allow people to necessarily acknowledge this, especially those who did not attempt to overcome such an obstacle. In both units, the ooids are partly leached. More specifically, the ooid cortices were partly leached and some ooid nuclei appear suspended in the middle of cortical moldic cavities created by leaching, rather than having fallen to the bottom of these cavities before the final cementation take place.
We demonstrate that these ooids were originally calcitic, not aragonitic, not "two-phase" nor "bimineral". Several hardgrounds and oolitic pebble-cobble layers in the succession are encrusted and bored. Some worm borings have rough walls, where early marine fibrous cement is less corroded than the cortices of cemented ooids. The key to understanding this differential dissolution could be related to organic matter, present within the ooid cortices but lacking in the fibrous cement.
Polychaete worms that use chemical means enzymes or acids to bore are probably responsible for these peculiar borings. A secondary conclusion is that partly or fully leached ooid cortices do not necessarily indicate an original aragonitic mineralogy of the dissolved parts. However, until now, this unit was lacking a clear definition. We introduce herein the Jezzinian Regional Stage, the type-locality of which is at Jezzine.
It equates as an unconformity-bounded unit and, per definition, it is framed by two discontinuities. Because we identified an additional, median sequence-boundary, poorly-expressed in the type-section but better at Aazour, only 4. The lithostratigraphic framework being properly redefined, we were able to investigate time-constrained micropaleontological assemblages, consisting mostly of benthic foraminifers and calcareous algae.
Typically Southern Tethysian, these assemblages contribute to high-resolution, holostratigraphic correlations with the Persian Gulf area, on the eastern part of the Arabian Plate. The Jezzinian interval correlates with the upper part of the Kharaibian Regional Stage also known as "Thamama II" reservoir unit in the oil industry.
In turn, the Jezzinian is indirectly correlated with the Northern Tethysian Urgonian stratigraphic units where it corresponds to a rather short interval encompassing the standard Barremian - Bedoulian stage boundary. Locally the upper discontinuity is associated to a significant intra-Bedoulian hiatus. The macrofossil assemblages found in the Jezzinian echinids and above it ammonites support, or at least do not contradict, our micropaleontological dating.
The Family Perisphinctidae is represented by Choffatia isabellae Bonnot et al. Thanks to the abundance and quality of the material, it was possible to describe and figure macroconchs and microconchs of these three species, including adult specimens with preserved peristome. The stratigraphical ranges of these taxa are also specified and their potential descendants can be considered.
These species are unknown in the uppermost Middle Callovian, and we assume that they colonized the northwestern part of the European platform via the southern margin of the Tethys, as did Peltoceras marysae Bonnot et al. Several recognized nannofossils have a stratigraphic distribution within the lower Danian. The assemblage of nannofossils and associated foraminifera is here discussed taking into account biostratigraphic and paleoecological aspects. Ostracodes from the Upper Cretaceous deposits of the Potiguar Basin, northeastern Brazil: taxonomy, paleoecology and paleobiogeography.
Part 2: Santonian-Campanian Enelise K. The following new species were described: Triebelina anterotuberculata , Triebelina obliquocostata , Cophinia ovalis , Fossocytheridea potiguarensis , Ovocytheridea anterocompressa , Ovocytheridea triangularis , Perissocytheridea jandairensis , Semicytherura musacchioi and Protocosta babinoti. The faunal association indicates predominantly shallow marine environments, intercalated with typically mixohaline levels. These species are mostly endemic, although the presence of six species common to West and North Africa shows that migration was still possible by the end of the Cretaceous.

This study combines a reappraisal of the literature with a unique first-hand source of data on the richest marine group the gastropods from over a 25 million year period Early Oligocene to Late Miocene. In total the French deposits have yielded more than 10, species from the Eocene to the Upper Miocene. Evidence of significant bias in the fossil record is pointed out for the Palaeocene Danian and Upper Eocene Priabonian. For the period considered Palaeocene to Late Miocene, ca 50 million years the second highest diversity is reported in the Late Oligocene.
This study reveals also the importance of pre-Miocene extinctions of genera. The Oligocene was when the latitudinal differentiation of the faunas was greatest. The local generic gastropod richness ranges from 59 Rupelian of Belgium to Chattian of Aquitaine.
The Clouds Still Hang Series by Patrick C. Notchtree
A clear trend towards homogenization appears in the Late Oligocene which leads to the development of a vast biogeographical region named Euro-West Africa. This faunal evolutionary pattern has never been demonstrated before and is a novel feature of the biogeography of the Eastern-Atlantic region. Origin of the Tethyan Hemihoplitidae tested with cladistics Ancyloceratina, Ammonoidea, Early Cretaceous : an immigration event?
Their rapid evolution and diversification make them one of the key groups for that period, but their origin remains poorly known and several competing hypotheses have been published. These hypotheses are tested here with cladistic analysis in order to reject those receiving the least support and discuss those well supported.
The analysis discards the Crioceratitidae, Emericiceratidae Emericiceras and Honnoratia and Toxancyloceras as stem-groups of the Hemihoplitidae Gassendiceras. The Toxancyloceras appear instead to be a sister-taxon of the Moutoniceras , so we propose the latter to be classified with the Ancyloceratidae rather than with the Heteroceratidae.
The best supported hypothesis assumes that the Hemihoplitidae first appeared suddenly in the Essaouira-Agadir Basin at the end of the Early Barremian from small populations of Boreal Paracrioceras. These latter could have migrated southward episodically before invading the northern Tethyan margin at the beginning of the Late Barremian. As a consequence, the Paracrioceratidae fam.
Part 1: Turonian Enelise K. The new species include Cophinia grekoffi , Fossocytheridea tiberti , Haughtonileberis dinglei , Hemicytherura viviersae , Jandairella obesa new genus and species , Loxocorniculum? The diversity and dominance indexes vary according to the paleoenvironment. Three assemblages were identified: a predominantly mixohaline fauna in the basal part of the section, followed by a diversified shallow marine fauna and, in the upper part, a marine and brackish water ostracode fauna. Most of the recorded species are endemic.
Eight species are common to Northwest and North Africa, indicating a faunal link during the Turonian. The study of the Turonian faunas of the Potiguar Basin represents a significant improvement to understand the dynamic evolution of the Brazilian basins and the paleobiogeographical relationship with other regions.

The carbonate sequence cored from a borehole drilled in the central part of the Transylvanian Depression yields microfossil assemblages dominated by benthic foraminifera. These new data unequivocally document the presence of characteristic Berriasian-Valanginian taxa in these deposits.
Buchavalites sp. The agnostid is associated with an ichnofossil of the feeding trace classified as Arachnostega -type behaviour. The enrolled attitude of the agnostid exoskeleton suggests that the specimen is a carcass rather than moult. This additional example supports a benthic mode of life in the agnostid P. The studied association of feeding tunnels of an unknown Arachnostega -strategist and Peronopsis preserved inside a hyolithid conch is a case of "frozen" behaviour.
A new tool is proposed to constrain both the approaches. A new useful constraint emerges: to any absolute age assumed for the K-Pg boundary corresponds a value of the mean Cenozoic kyr period, and vice versa. Supposing a K-Pg boundary radiometric age in the vicinity of When adding to this figure the parts of the cycles preceding and following these entire cycles the total duration of the Cenozoic Era becomes equal to We propose to grant a special interest to the determination of the kyr cycle phase at stratigraphically well documented levels, particularly those that correspond to world-wide, sudden and catastrophic events, that are well located in time by reliable radiometric dates.
Novocrania turbinata synonym of N. The history of this species, commonly considered as the Mediterranean form of N. Recently, several authors have described N. After analysis of the taxonomic validity of these characters, both species are considered as synonymous. That is supported by their occurrence in various localities, mainly in the continental shelf. Their synonymy has been corroborated by molecular analyses and is discussed with reference to the characteristics of the Mediterranean basins and their history since the Miocene.
Sporolithaceae, Sporolithales, Rhodophyta , a million year old fossil coralline red alga from north-eastern Brazil, and a new Hauterivian record of Sporolithon from Switzerland William J. Sporolithaceae, Sporolithales, Rhodophyta , representing the first confirmation of the genus in the fossil record, were discovered in thin sections of Albian limestones from the Riachuelo Formation, Sergipe Basin, and in thin sections of Albian - Cenomanian limestones from the Ponta do Mel Formation, Potiguar Basin in north-eastern Brazil.
A detailed morphological-anatomical account of the species is provided, and its placement in Heydrichia is discussed in relation to current classification proposals. Comparisons with the four other known species of the genus, all non-fossil, show that H. The evolutionary history of Heydrichia remains uncertain, but available data suggest that the genus may have diverged from the sporolithacean genus Sporolithon , known as early as Hauterivian times c.
Current data also suggest that Heydrichia is more likely to have arrived in Brazil from Central Atlantic waters than from higher latitude South Atlantic waters. This implies that currently living species in southern Africa probably arose later from ancestors further equatorward in the South Atlantic, although confirming studies are needed. All non-fossil species of Heydrichia are known only from the southern hemisphere.
The new standard division of the segment C7 is based on a revision of published Barremian-Aptian carbon isotope curves from stratigraphic sections of the Prebetic Domain in Spain. It includes four distinct isotopic subunits labeled C7a to C7d, with a characteristic negative carbon isotope excursion at the base of the segment and which correlates with the Dufrenoyia furcata ammonite Zone.
We provide possible sites correlatable with the IFNE in both the Old and New worlds, which suggest its potential use as an even global chemostratigraphic marker for the Aptian record. Two formations are recognised in the clay facies the "Gault" auct. The type area of the Albian stage is of great interest because of the size of the clay facies more than m unique in the Anglo-Paris basin.

James was his soulmate and the friendship they shared made me value the love that comes not from sex but from a place too intimate to even fully understand.
Having finished this book with a teary-eyed smile on my face, I can safely say that the story of Simon is not one I will ever forget. I raise my glass to him, to Daniel, to James, to all of those that kept Simon alive; may they all have the endings they hoped for, wherever they may be in the world, after the book closes and things come full circle off the pages. Feb 10, Leland Hall rated it really liked it. The Clouds Still Hang by Patrick C Notchtree—a reaction from Eldot I write this rather urgently, just after reading the entire eBook—my hunch is that upon reflection I might not be as honest.
This is from the gut. The first novel, The Book of Daniel was one of the more enjoyable reads I have had in some time. It has all the elements required for engaging and involving the reader. At times it seemed hurried and incomplete, but it was strong enough to keep me involved—so much so that I was able to s The Clouds Still Hang by Patrick C Notchtree—a reaction from Eldot I write this rather urgently, just after reading the entire eBook—my hunch is that upon reflection I might not be as honest.
I was unsatisfied when I came to the conclusion, but the knowledge that it was the first of a trilogy mollified. I immediately went to the LULU site and bought the complete book in both the print and eBook versions. That attests to how eager I was to follow the story of Simon and Daniel, and how obligated I felt to the author for providing me with such a wonderful experience. The Story of Daniel could have been a superb novel, had that been the objective. That would have alerted me to the fate of the narrative that was to follow. I hope that one day the author will be done with catharsis and write The Story of Daniel and Simon.
That is the story I was expecting, but which was replaced by clinical therapeutic reportage. Sadly, that becomes more a sales device than a meaningful structure. There is enough raw material in The Clouds Still Hang for several novels. That would require authoring at a different level certainly, and a supervisory detachment about the proceedings that allows insights to mature and attain dominance.
There is a crippling dependence on chronology and detail that keeps the reader at arms length at least, and prevents engagement. The main reason I finished reading the set was because of what the author provided in part 1.

It enabled me to stick with it, though to what end I am not sure. How sad is all I can say, really. My recommendation to the author: finish the first part properly on its own terms. It is worthy and worth doing—another 40 to 60, words, I think would serve nicely. Make fiction your friend. View all 3 comments. Feb 09, Alan Hardy rated it really liked it. The early part of the tale explores the relationship between Simon and his slightly older friend Daniel in infant-school days, and their growing homosexual rapport.
Although that life is explored in great detail rites of passage, transition to adulthood, work, marriage, etc.

Simon suffers greatly from depression and low self-esteem, and yet, by the end of the book, the stance is more decidedly positive: Simon achieves a measure of contentment through an acceptance of the duality of his nature, that he can love deeply his wife of many years at the same time as being unashamed of homosexual loves both in his past and present. There are no easy answers offered, but the struggle itself which the book is an expression of seems to be held up as achievement and accomplishment enough. Can any of us really hope for more from life? View 2 comments.

I've thought about writing a review for this book for at least a couple of months and in the end have decided there's nothing more I can add to what's already been written by Leland Hall. That parts two and three serve a mainly cathartic purpose is clear. In part one we see at the end Simon almost completely dependent on Daniel and throughout Simon's life, even though Daniel is absent, nothing changes.
So Patrick, my advice is to develop parts two and three into something more than chronologies an I've thought about writing a review for this book for at least a couple of months and in the end have decided there's nothing more I can add to what's already been written by Leland Hall. So Patrick, my advice is to develop parts two and three into something more than chronologies and, as Leland Hall says, add 40, to 60, words to part one, make it a book unto itself, The Book of Daniel so that it rises from good to great.
