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 conŪrms the widespread
distribution of Bolosauridae across Laurasia during this early stage of
amniote evolution.  Eudibamus cursoris is the oldest known representative of
Parareptilia, a major clade of reptiles.
