|Chameleo chameleo from Samos, Greece.. Benny Trapp|
The Chamaeleonidae fossil record is very scarce and any new specimen is therefore considered important for our understanding of the evolutionary and biogeographic history of the group. In a new paper Georgalis et al. (2016) report on new specimens from the early Miocene of Aliveri (Evia Island) in Greece. These are the only fossils chamaeleons from southeastern Europe. Although skull bones are tentatively attributed to the Czech species Chamaeleo cf. andrusovi, revealing a range extension for this taxon, the tooth-bearing bones are described as indeterminate chamaeleonids. The Aliveri fossils rank well among the oldest known reptiles from Greece, provide evidence for the dispersal routes of chameleons out of Africa towards the European continent and, additionally, imply strong affinities with coeval chamaeleonids from Central Europe.
