Nuevos restos de caparazones de «Peltochelys duchastelli» (Dollo, 1884) de Europa Occidental y Central e incremento de los Trionícidos (Testudines: Trionychoidea)

Abstract

Turtle remains, first described by graBBe (1883) as Tretosternon punctatum Owen, 1842 from the early Cretaceous of Northwest Germany, are redescribed in detail. The material belonging to the species Peltochelys duchastelli dollo, 1884 consists of some natural molds of carapace remains with a fine scar like surface, these remains are enclosed in the historic material which has been collected by Heinrich Friedrich Wilhelm Grabbe during the investigations for his doctoral thesis in the late 19th Century. The fossils are stored in the collections of the Geoscience Centre of Georg-August-University Göttingen, Germany. New material from Germany and Portugal is described, and the material from the Guimarota mine is revised. The material which is described here gives evidence of soft shelled turtle evolution.
