Cryptostomata (Bryozoaires) des "calcaires à Polypiers siliceux" (Dévonien inférieur de la Montagne Noire, France méridionale). Note préliminaire
No full textThe formation so-called "Calcaires à Polypiers siliceux" yielded finely silicified Bryozoa which would present affinities with those of Zlichov Beds in Bohemia (Upper Emsian). Besides fragmentary zoaria of Trepostomata and Cystoporata, the population consists of Cryptostomata here described in a preliminary report.La formation des "Calcaires à Polypiers siliceux" de la nappe du Pic de Bissous (près de Cabrières, Hérault) a livré une faune de Bryozoaires finement silicifiés qui présenterait des affinités avec celle des Calcaires de Zlichov en Bohême (Emsien supérieur). Cette faune se compose surtout de Cryptostomata, qui font l'objet de cette étude préliminaire, mais aussi de Trepostomata et de Cystoporata. Les zoaria se présentent à l'état de fragments.Bigey Françoise, Feist Raimund.

Biodiversity, distribution and patterns of extinction of the last odontopleurid tilobites during the Devonian (Givetian, Frasnian)
No full textBiostratigraphical ranges and palaeogeographical distribution of mid-Givetian to end-Frasnian odontopleurids are investigated. The discovery of Leonaspis rhenohercynica sp. nov. in mid-Givetian strata extends this genus unexpectedly up to the late Middle Devonian. New material of Radiaspis radiata (Goldfuss, 1843) and the first koneprusiine in Britain, Koneprusia? sp., are described from the famous Lummaton shell-bed, Torquay, Devon. New taxa of Koneprusia, K. serrensis, K. aboussalamae, K. brevispina, and K. sp. A and K. sp. B are defined. Ceratocephala (Leonaspis) harborti Richter & Richter, 1926, is revised and reassigned to Gondwanaspis Feist, 2002. Two new species of Gondwanaspis, G. dracula and G. spinosa, plus three others left in open nomenclature, are described from the late Frasnian of Western Australia. A further species of Gondwanaspis, G. prisca, is described from the early Frasnian of Montagne Noire. Species of Gondwanaspis are shown to possess a number of paedomorphic features. A functional analysis suggests that, unlike other odontopleurids, Gondwanaspis actively fed and rested with the same cephalic orientation. The sole odontopleurid survivors of the severe terminal mid-Givetian biocrisis (‘Taghanic Event’) belong to the koneprusiine Koneprusia in the late Givetian and Frasnian, and, of cryptogenic origin, the acidaspidine Gondwanaspis in the Frasnian. Whereas the former became extinct in the late Frasnian at the Lower Kellwasser Event, the latter disappeared, and with it the entire Odontopleuroidea, at the terminal Frasnian Upper Kellwasser global biocrisis
The micrometeorite flux to Earth during the Frasnian-Famennian transition reconstructed in the Coumiac GSSP section, France
No full textWe have reconstructed the distribution of extraterrestrial chrome spinels in a marine limestone section across the Frasnian-Famennian stratotype section at Coumiac in southern France, providing the first insights on the types of micrometeorites and meteorites that fell on Earth at this time. The data can test whether the small cluster of roughly coeval, large impact structures is related to an asteroid breakup and shower with possible bearings also on the late 26 Devonian biodiversity crisis. A total of ~180 extraterrestrial spinel grains (>32 microns) were recovered from 957 kg of rock. Noble-gas measurements of individual grains show high solar-wind content, implying an origin
from decomposed micrometeorites. Element analyses indicate a marked dominance of ordinary chondritic over achondritic grains, similar to the recent flux. The relation between H, L and LL meteorites is ~29-58-13%, similar to the late Silurian flux, ~31-63-6%, but different from the distribution, ~45-45-10%, in the recent and the Cretaceous flux. Our data show no indication of a generally enhanced late Devonian micrometeorite flux that would accompany an asteroid shower. However, in a single limestone bed that formed immediately before the Upper Kellwasser horizon, that represents the main end-Frasnian species-turnover event, we found an enrichment of ~10 ordinary chondritic grains (>63 microns) per 100 kg of rock, compared to the ~1-3 grains per 100 kg that characterize background. The anomalously abundant grains are of mixed H, L and LL types and may be related to an enhanced flux of extraterrestrial dust during postulated minima in both the 405 ka and 2.4 Ma Earth-orbit eccentricity cycles at the onset of the Upper Kellwasser event. In the present solar system the dust accretion at Earth is the highest at eccentricity minima because of the spatial distribution of dust bands of the zodiacal cloud. Besides this small grain anomaly the data here and in previous studies support a stable meteorite flux through the late Silurian and Devonian, in contrast to the mid-Ordovician, when achondritic meteorites that are rare on Earth today were common, followed by the influx of a flood of debris related to the breakup of the L-chondrite parent body. Our accumulated data for six time windows through the Phanerozoic indicate that the ordinary chondrites make up a major fraction in the meteorite flux since at least the mid-Ordovician. We note that the sources in the asteroid belt of the H and L3 meteorites, the two most common types of meteorites today and through much of the Phanerozoic, remain elusive
Post-Kellwasser event recovery and diversification of phacopid trilobites in the early Famennian (Late Devonian)
No full textInternational audienceWhile no Frasnian phacopid genera are known to survive the terminal Frasnian Kellwasser extinction event, recovery of phacopids in the early Famennian is characterised by one of the highest origination rates of the clade. In this study species and subspecies currently known are updated with regard to their age distribution according to conodont-based bio-zonation. They occur in representative sites including Sessacker (Rhenish Slate Mountains), Wieda (Harz), McWhae Ridge (Canning Basin, Western Australia), Beni Abbes (Algerian Sahara) and Montagne Noire (Southern France). More than two-thirds of the taxa are reduced-eyed or blind, which might indicate adaptation to deep offshore habitats. A few taxa with Phacops-like kidney-shaped eyes with many lenses represent shallower environments in the photic zone. The fauna is characterised by different features of the ventral cephalic doublure due to the presence or absence of individualized anterior border, vincular furrow and postvincular doublure. Phyletic affiliation to Frasnian taxa remains difficult to assess until these are better known for their diversity in various habitats. Chlupacops may be a possible ancestor of taxa with cephalic anterior border such as Nephranops and Houseops, while Cryphops and Trimerocephalus may be rooted in Acuticryphops as previously thought. The systematic part is devoted to diagnoses and descriptions that are completed by new morphological criteria leading to some taxonomic re-assignments. The following taxa are new: Nephranops (Nephranops) angerae sp. nov., Nephranops (Maternia) occitanicus subgen. et sp. nov., Pulvinocephalus gen. nov., P. (Pulvinocephalus) steinachensis triangulus subgen. et subsp. nov., P. (Cryphopsides) ovatus subgen. et sp. nov., P. (?Cryphopsides) walliseri ?subgen. et sp. nov., Trifoliops septimanicus sp. nov., Struveops wiedaensis sp. nov
So mechanical or routine: The not original in Feist
No full textThe United States Supreme Court case of 1991, Feist Publications, Inc. v. Rural Tel. Service Co., continues to be highly significant for property in data and databases, but remains poorly understood. The approach taken in this article contrasts with previous studies. It focuses upon the “not original” rather than the original. The delineation of the absence of a modicum of creativity in selection, coordination, and arrangement of data as a component of the not original forms a pivotal point in the Supreme Court decision. The author also aims at elucidation rather than critique, using close textual exegesis of the Supreme Court decision. The results of the exegesis are translated into a more formal logical form to enhance clarity and rigor.The insufficiently creative is initially characterized as “so mechanical or routine.” Mechanical and routine are understood in their ordinary discourse senses, as a conjunction or as connected by AND, and as the central clause. Subsequent clauses amplify the senses of mechanical and routine without disturbing their conjunction.The delineation of the absence of a modicum of creativity can be correlated with classic conceptions of computability. The insufficiently creative can then be understood as a routine selection, coordination, or arrangement produced by an automatic mechanical procedure or algorithm. An understanding of a modicum of creativity and of copyright law is also indicated.The value of the exegesis and interpretation is identified as its final simplicity, clarity, comprehensiveness, and potential practical utility.<br/
