Abstract

The turtle “Pleurosternon” [“Glyptops”] typocardium (Seeley, 1869) from the Early Cretaceous (Berriasian) Purbeck Limestone Group of England is selected as type species of Ballerstedtia n. gen. The new genus is characterized by a deep nuchal notch and an estimated carapace length of only 0.3 m, what is in representatives of contrary to the large genera Pleurosternon and Hylaeochelys. Furthermore, Ballerstedtia bueckebergensis n. sp. from the Wealden Facies of northwestern Germany (Berriasian) is described and included in this new genus. The relationships of these two nearly contemporaneous species are also analyzed.
