Saxonagrion minutus nov. gen. et sp., the oldest damselfly from the Upper Permian of France (Odonatoptera, Panodonata, Saxonagrionidae nov. fam.)
1999
Abstract Saxonagrion minutus nov. gen. et sp. was found in the Saxonian (Salagou Formation) of the Lodeve basin. It is the oldest and the first record of the modern infra-order Panodonata in the Palaezoic (Upper Permian of France). The present discovery supports the hypothesis concerning the persistance of many groups of Odonatoptera through the Permo-Triassic boundary.
Découverte d'Arthropodes et de bivalves inédits dans le Permien continental (Lodévois, France)
1997
Resume Des Triopsides, Conchostraces, Insectes, Bivalves, pistes et terriers d'Arthropodes sont decouverts dans le Groupe saxonien considere longtemps comme quasi azoique. Ces fossiles sont pour la plupart inedits, au niveau de l'espece, de la famille et de l'ordre. Chez les Insectes, de nouveaux taxons comblent des lacunes temporelles considerables, allant du Jurassique au Permien. Les informations recueillies vont permettre de rediscuter certaines phylogenies et de reapprecier l'impact de la crise fini-permienne sur cette classe. La repartition des Insectes et des Conchostraces suggere de donner un âge Koungourien a Tatarien (Leonardien a Capitanien) au ≪ Saxonien ≫.
Biocénoses à triopsidés(Crustacea, Branchiopoda) du Permien du bassin de Lodève (France)
1997
Resume Nous decrivons les triopsides (Crustacea, Branchiopoda) qui abondent dans les facies “saxoniens” de la Formation du Salagou du bassin de Lodeve date “Thuringien” ou “Saxonien” selon les auteurs. A partir de milliers de debris de carapaces, d'axes thoraco-abdominaux et plus rarement a partir d'animaux entiers, nous avons identifie et decrit deux especes nouvelles: Triops cancriformis permiensis nov. ssp. et Lepidurus occitaniacus nov. sp., morphologiquement proches d' especes actuelles. En se basant sur les preferences ecologiques des triopsides actuels et les caracteristiques sedimentologiques de leur milieu de vie au Permien, nous avons confirme l'existence d'etendues d'eau, peu pro…
Deux nouvelles traces de pas de Dinosaures du Trias supérieur de la bordure cévenole (la Grand-Combe, Sud-Est de la France)
2000
Resume Dans une formation sommitale a Argiles bariolees du Trias superieur francais, deux niveaux a traces depas inedites de Dinosaures ont ete decouverts. Elles se rapportent a l'association Otozoum/Grallator qui n'a jamais ete definie precisement en Europe. Sa position stratigraphique precise dans la serie triasique et la comparaison avec les associations ichnologiques des USA et d'Afrique du Sud, confirment l'âge Norien des niveaux a empreintes. Otozoum grandcombensis nov. ichnosp. correspond a des traces de pieds et de mains tetradactyles de meme taille, laissees par un animal bipede occasionnellement quadrupede. Il s'agissait probablement d'un, grand Prosauropode, d'une dizaine de m de…
The first recorded protozygopteran insects from the Upper Permian of France
1999
. The earliest known Odonatoptera: Protozygoptera from the Upper Permian of Lodeve (France) are described. Epilestes gallica sp. nov. belongs to the Permolestidae and Lodevia longialata gen. et sp. nov. to the Permepallagidae. Both of these families were previously known from the Kazanian of Russia, suggesting a similar age for the formation of Lodeve.
Discovery of an Autunian macroflora and lithostratigraphic re-investigation on the western border of the Lodève Permian basin (Mont Sénégra, Hérault,…
2013
11 pages; International audience; Re-investigation of the western edge of the Lodève basin allows reassignment of one sandstone-conglomerate formation previously identified as "terminal Stephanian" to Early Autunian. The existence of two unconformable (Stephanian and Autunian) megasequences, separated by a sedimentary gap, which had been rejected, is thus re-affirmed. The authors also found, less than 20 m above the basal Autunian conglomerate, a macroflora with taxa characteristic of the famous Tuilières flora from a site, located in the eastern part of the basin near Lodève, in the Grey Autunian group. This confirms that the new Mont Sénégra fossiliferous beds belong to the Lower Autunian…
A new family of Odonatoptera from the continental Upper Permian: The Lapeyriidae (Lodève Basin, France)
1999
Abstract The new family Lapeyriidae of Odonatoptera, based on a new genus and species from the Upper Permian of Lodevois (France) is the sister group of Nodialata. It represents an evolutionary link between the venation type of the Paleozoic Meganisoptera and that of Odonata. Even if the present discovery demonstrates that the fossil record of the Odonatoptera remains imperfectly known, the present state of knowledge shows that this super order survived the mass extinction at the Permo-Triassic boundary.
Notostraca trackways in Permian playa environments of the Lodève basin (France).
2008
36 pages; International audience; For nearly 20 years, Dr. Lapeyrie, surgeon at Lodève, has gathered many fossils coming from the Salagou Formation of the Lodève Permian basin. They are Insects, Notostraca, plants and ichnofossils. Among the latter, appears a multitude of Arthropoda trackways, finely preserved, which were collected in the top of sequences deposited in a playa environment. The locomotion experiments undertaken with extant animals suggested allocation of the majority of these trackways to Notostraca which are also known by several hundreds of remains (carapace, appendages, body whole). From these different parts, it was described as Triops cancriformis permiensis and Lepiduru…
