Late Cretaceous vertebrate paleobiogeography in Europe

Late Cretaceous continental sedimentary rocks are becoming rare in Europe…

Inferred phylogenetic relationships and paleogeographic distribution of bothremydid turtles during the Late Createcous of Europe. Interestingly, preliminary results suggest that one of the French turtles (Foxemys mechinorum) is more closely related to the turtle from Iharkút, Hungary (Foxemys trabanti) than to the other French turtles (Polysternon, Elochelys). However, studies on the phylogenetic relationships of Late Cretaceous European vertebrates are in a very preliminary state and these results are likely to change in light of future analyses and discoveries.
