Although extremely endemic at the species level, the Haţeg fauna is part of a larger Received in revised form 15 December 2009 European palaeobioprovince compared to roughly contemporary (Campanian–Maastrichtian) terrestrial Accepted 10 March 2010 faunas elsewhere in Europe. Phylogenetic analyses of five Haţeg taxa, calibrated by biostratigraphic Available online 16 March 2010 occurrences provide evidence of long ghost lineages. The geographic distributions of kogaionids, Kallokibotion, Allodaposuchus, and Zalmoxes (together with their European sister taxa) may have arisen Keywords: Haţeg Basin from vicariant events between western Europe and North America, while the distribution of Telmatosaurus is Vertebrate fauna an example of European endemism of Asiamerican origin. Late Cretaceous While Haţeg seems to have acted as a dead-end refugium for Kallokibotion and Telmatosaurus, other faunal Palaeobiogeography members (and their immediate sister taxa) are not restricted to Transylvania, but known otherwise from Evolution localities across southern Europe.
