In Southern Europe (France and Spain), some localities are also known, but all have only yielded small faunas, composed by few taxa. An exception is the rich locality of Mas de Gimel (city of Montpellier, Hérault, France), which has long been considered the reference fauna of the late Ypresian in Southern Europe. Curiously however, only the rodents, artiodactyls and metatherians from this key locality have been studied in detail since the 1960s. Here, based on the original collection housed in the University of Montpellier, we revise the entire mammal taxa, which leads us to identify 38 species among 12 orders. We also study the close and co-eval localities of Naples and Naples 2, where we identify 23 species among 10 orders. Among the species identified from the three localities, we describe the new theridomorph rodent Hartenbergeromys pailladensis n. sp., characterized by numerous thin high extra ridges on upper and lower molars.

Vullo, Elsie Bichr, Jérôme Thomas, G. Gand, Cyril Gagnaison, Pascal Barrier, Didier Néraudeau","doi":"10.5252/geodiversitas2024v46a8","DOIUrl":"https://doi.org/10.5252/geodiversitas2024v46a8","url":null,"abstract":"ABSTRACT The coastline of Le Veillon (western France) has become a key tracksite for the study of Early Jurassic archosaurs from Europe since the second half of the 20th century. Amongst the thousand dinosaur footprints recovered from this locality, some tracks became historical and ichnotaxonomical comparative references in many studies. However, the type material from Le Veillon has never been revised. Here, we reinvestigate the type specimens from Albert-Félix de Lapparent's collection using morphometry and 3D imaging photogrammetry. Amongst the eight ichnospecies historically created at Le Veillon, only two are considered valid, i.e. Grallator olonensis Lapparent & Montenat, 1967 and Grallator variabilis Lapparent & Montenat, 1967. “Batrachopus gilberti” Lapparent & Montenat, 1967, “Eubrontes veillonensis” Lapparent & Montenat, 1967 and “Grallator maximus” Lapparent & Montenat, 1967 are subjective junior synonyms of Batrachopus deweyi (Hitchcock, 1843) Hitchcock, 1845, Eubrontes giganteus Hitchcock, 1845 and Grallator minusculus (Hitchcock, 1858) Demathieu, Gand, Sciau & Freytet, 2002, respectively. The ichnogenus “Talmontopus” Lapparent & Montenat, 1967 is a subjective senior synonym of Kayentapus Welles, 1971, and its type ichnospecies (“T. tersi” Lapparent & Montenat, 1967) is regarded as a nomen dubium. “Anatopus” Lapparent & Montenat, 1967 (and its type ichnospecies “A. palmatus” Lapparent & Montenat, 1967) and “Saltopoides” Lapparent & Montenat, 1967 (and its type ichnospecies “S. igalensis” Lapparent & Montenat, 1967) are considered as nomina dubia. The tracks initially ascribed to Dahutherium Montenat, 1968 are here reinterpreted as Batrachopus isp. and indeterminate grallatorid tracks. The ichnoassemblage from Le Veillon is more similar to tracks from the Grands Causses area (southern France) than to any other Lower Jurassic ichnoassemblage in Europe. Although contemporaneous body fossils remain unknown in Vendée, the archosaur tracks from Le Veillon confirm the co-occurrence of crocodylomorphs and theropods in littoral environments from the central part of Laurasia during the Hettangian.

Depuis la seconde moitié du XXe siècle, le littoral du Veillon (ouest de la France) est devenu un site capital pour l'étude des traces de pas d'archosaures du Jurassique inférieur d'Europe.

Valeč-Šibeniční Vrch is located on the south-eastern periphery of the complex Doupovské Hory shield volcano (North Bohemia), and is formed by volcanosedimentary series. The hemi-mandible was found in pyroclastic deposits under the laminated limestones, from which so-called “rodent from Valeč” originated.

Lors des travaux de terrain en 2017, une hémi-mandibule gauche de carnivore a été trouvée dans la localité de Valeč-Šibeniční Vrch (= Waltsch-Galgenberg), en République tchèque.

In East Asia, crayfishes are represented by a single family, Cambaroididae Villalobos, 1955 with a single genus, Cambaroides Faxon, 1884 which phylogenetic relations to other northern hemisphere crayfishes has been debated. Here, we review crayfishes from the Early Cretaceous Jehol biota, China, where three species of crayfishes have been described from. We observed that specimens correspond either to exuviae or body fossils, the later sometimes including preserved gastroliths. Our investigation also shows it is not possible to find any distinction between the species, leading to only one species to be recognized in the Jehol biota. Furthermore, the extinct family Cricoidoscelosidae Taylor, Schram & Shen, 1999 and its unique genus Cricoidoscelosus Taylor, Schram & Shen, 1999 are based upon characters insufficient to warrant a separate family. Perhaps the most important of these, the annulated pleopods is a plesiomorphic character of Astacoidea, with annulations most likely more visible due to fossilization. In fact, based upon the shape of the male gonopods and epistome, the general habitus, the possible presence of an annulus ventralis in females and ischial hooks in males, crayfishes from the Jehol biota can be assigned to Cambaroididae, which are currently restricted to East Asia. This suggests that members of Cambaroididae have inhabited East Asia since at least the Early Cretaceous. RÉSUMÉ Écrevisses du biote de Jehol. Les écrevisses sont des invertébrés d'eau douce bien connus: elles sont importantes économiquement, du point de vue de l'écologie, et ont également un fort impact culturel. À l'est de l'Asie les écrevisses sont représentées par une seule famille, les Cambaroididae Villalobos, 1955, comprenant un seul genre, Cambaroides Faxon, 1884, dont les relations phylogénétiques avec les autres écrevisses de l'hémisphère nord sont encore mal comprises. Nous révisons ici des écrevisses du biote de Jehol (Crétacé inférieur) parmi lesquelles trois espèces ont été décrites. Nous observons que les spécimens correspondent soit à des exuvies, soit à des corps, ces derniers incluant parfois des gastrolithes. Notre travail montre aussi qu'il n'est pas possible de différencier ces trois espèces, suggérant ainsi qu'une seule espèce est présente dans le biote de Jehol. De plus, la famille fossile de Cricoidoscelosidae Taylor, Schram & Shen, 1999, et son unique genre Cricoidoscelosus Taylor, Schram & Shen, 1999 s'appuient sur des critères insuffisants pour justifier son maintien. Le plus important de ces critères, les pléopodes annelés, est plésiomorphe pour les écrevisses; par ailleurs, la fossilisation accentue la visibilité de ces annulations.
