Asilisaurus (pronounced a-see-lee-sawr-us;meaning "foundation" or "ancestor lizard") is an extinct genus of recently described silesaurid archosaur. It is the oldest avian-line archosaur, dating to about 245 million years ago. The type and only genus is A. kongwe.

Discovery[]

Fossils were uncovered in Tanzania and date back to the Anisian stage of the Middle Triassic period. It was described in 2010 by a team of researchers from the U.S., Germany, and South Africa, in the journal Nature. It is the first example of an avian-line radiation during the Anisian; with the diversification of archosaurs during this time previously only documented from crocodilian-like archosaurs. It is the first non-dinosaurian dinosauriform recovered from Africa.

Description[]

Asilisaurus measured from 3–10 feet long and 2–3 feet high at the hip, weighed 20-70 pounds.
