Eudibamus cursoris

Eudibamus is an extinct genus of bolosaurid reptile known from the Early Permian of the Free State of Thuringia in central Germany. It was a small reptile, only 25-26 cm in length. Like other bolosaurids, it was probably an agile herbivore, and it shows a long list of adaptations for bipedal (two-legged) movement. The hindlimbs had a parasagittal stance, with close-set and nearly vertical legs similar to dinosaurs and mammals. The tail and hindlimbs are very long, the forelimbs are slender, the digits are closely bundled together, and the ankle joint is hinge-like. Eudibamus is regarded as the oldest known bipedal vertebrate.

Time the record covers

At most 5.4 million years on record.

The one occurrence read is dated to somewhere between 298.9 Mya and 293.52 Mya, which is a dating window rather than a span.

1 occurrence of Eudibamus cursoris on record, most of them in the Permian. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

1 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.
