The vertebrate collection of the Museum of Paleontology and Geology of the University of Athens contains a complete skull of a wooly rhinoceros ( Coelodonta antiquitatis) and a molar of a wooly mammoth ( Mammuthus primigenius). They were described and figured by Melentis (1961, 1966) as elements of the Pleistocene fauna, which was discovered near Megalopolis in the Peloponnesus (southern Greece). This skull of Coelodonta is the only known specimen of the genus in Greece. There are two reports of uncertain occurances of the wooly mammoth, one from Macedonia and the other from Thessaly, both in northernmost Greece, but Megalopolis in southern Greece provides the only certain determination of the species in Greece (Doukas & Athanassiou, 1999).
