A stagodontid mammal from the mid-Cretaceous of France confirms the Euramerican distribution of early marsupialiforms

摘要: Abstract The global palaeobiogeography of early marsupialiform mammals is still poorly understood due to a meagre fossil record outside western North America. Here, two isolated teeth mammal from the lowermost Upper Cretaceous (lower Cenomanian) southwestern France are described and referred Stagodontidae, dentally specialized group whose unambiguous members so far known exclusively occurrence stagodontids in Europe represents additional evidence faunal exchanges between landmasses during latest Albian–early Cenomanian interval, around 100 million years ago, shows that (mid-Cretaceous) marsupialiforms were more widely distributed than previously thought.
