Archosauriform teeth from the upper Triassic of Saint Nicolas-de-Port (Northeastern France).Pascal Godefroit and Gilles CunyKeywords: Archosauriforms; Graoullyodon hacheti; Saint-Nicolas-de-port; Teeth; Upper TriassicAbstract The Late Triassic locality of Saint-Nicolas-de-Port (Meurthe-et-Moselle, France) has yielded numerous isolated teeth belonging to archosauriform reptiles. The following tooth groups can be identified: heterodont phytosaurs, the pterosaur Eudimorphodon, the prosauropod dinosaur Plateosaurus, three types of putative ornithischian teeth and 13 types of carnivorous Archosauriformes indet. Apparent venom-conducting teeth belonging to a new taxon of ?Archosauriformes (Graoullyodon hacheti nov. gen. nov. sp.) are also described. From a palaeogeographical point of view, the ornithischian teeth from Saint-Nicolas-de-Port (if their attribution is confirmed) are the oldest fossils of this group in Europe. The biostratigraphic distribution of the tooth forms mostly suggests a Late Norian or Early Rhaetian (depending on current interpretations) age of the deposits, but do not provide more precisions than fossils previously described from the area. The dietary habits and, consequently, the palaeoecological relationships of the different vertebrate groups discovered at Saint-Nicolas-de-Port are tentatively established: the ornithischian and prosauropod teeth reflect a herbivorous diet, whereas the other archosauriform teeth are probably from camivores or omnivores.

Revision des faunes de vertébrés du site de Provenchères-sur-Meuse (Trias terminal, Nord-Est de la France)Gilles CunyKeywords: amphibians; Fishes; Reptiles; Rhetian; TriassicAbstract Revision of ancient collections and study of new material from Provenchères-sur-Meuse (Rhaetian) lead to signíficant changes in the faunal list of this site. This bring to us important information about the effect of the rhaetian transgression on the evolution of the faunas at this period of time.
