Paleobiogeographical history of Prolagus, an European ochotonid (Lagomorpha)

Prolagus is one of the world's longest mammalian lineage, dwelling for more than 20 million years, 24 Ma if its direct ancestor Piezodus is taken into account, in Europe, Anatolia and northern Africa. Prolagus fossils form locally very rich assemblages, indicating that it was a common prey supp...
