U. ceibalii Powell, 1979 (type) |
Unquillosaurus (meaning "Unquillo river lizard") is a genus of maniraptoran dinosaur from the late Cretaceous Period, discovered in Argentina. Known only from a single fossilized pubis (hip bone), its total body length may have reached 2-3 meters (6-10 ft).[1]
The type species is U. ceibalii, described by Powell in 1979, and re-studied by Novas and Agnolin in 2004, who found that it likely belonged to the family Dromaeosauridae.[2][3]
