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