A new genus of ‘Ptychogasteridae’ (Chelonii, Testudinoidea) from the Geiseltal (Lutetian of Germany)

Among the fossil turtles from of the Lutetian locality of Geiseltal (Germany), a new taxon of freshwater Testudinoidea is described. This taxon belongs to the ‘Ptychogasteridae’ group, which is diagnosed here. It is a primitive taxon, allowing the polarization of the characters of this group. A hypothesis of relationships between European and North American forms in the ‘Ptychogasteridae’ group is proposed. To cite this article: S. Hervet, C. R. Palevol 3 (2004).
