Résumé The Rhaetian locality of Saint-Nicolas-de-Port (France) has yielded the most abundant and diverse mammalian assemblage
known from the Late Triassic. Most of the material remains undescribed. We review here the morganucodonts from Saint-
Nicolas-de-Port. We identify the upper and lower molariforms of the genus Brachyzostrodon. We also identify in the site
Morganucodon peyeri, previously known from the Late Triassic of Hallau (Switzerland), as well as the genera Paceyodon
and Paikasigudodon. The description of the new species Megazostrodon chenali sp. nov. extends the stratigraphical and
geographical range of the genus, previously known from the Early Jurassic of southern Africa. Finally, another new
morganucodont, Rosierodon anceps gen. et sp. nov., is described. The Morganucodonta is recognized as the most diverse
order of Late Triassic mammals. Current fossil data suggest that Europe was the centre of initial diversification of
morganucodonts at the end of the Triassic, and that morganucodonts were not much affected by the extinction event at the Triassic/Jurassic transition.
