Abstract

A 290-million-year-old reptilian skeleton from the Lower Permian (Asselian) of Germany provides evidence of abilities for cursorial bipedal locomotion, employing a parasagittal digitigrade posture. The skeleton is of a small bolosaurid, Eudibamus cursoris , gen. et sp. nov . , and confirms the widespread distribution of Bolosauridae across Laurasia during this early stage of amniote evolution. E. cursoris is the oldest known representative of Parareptilia, a major clade of reptiles.

1. The origin and early evolutionary history of amniotes

2. Etymology: Greek eu meaning original or primitive and dibamos meaning on two legs; Latin cursoris meaning runner. Holotype: MNG (Museum der Natur Gotha Germany) 8852. Horizon and locality: Lower Permian Tambach Formation Upper Rotliegend in the Bromacker quarry locality of the middle part of the Thuringian Forest near the village of Tambach-Dietharz and about 20 km south of Gotha Thuringia central Germany. Diagnosis: Small bolosaurid parareptile distinguished by the presence of long narrow boomerang-shaped postfrontal; three premaxillary teeth rather than two; interpterygoid vacuity narrow rather than closed; and dorsal lamina of maxilla low.
