Eodromaeus has been cited by Paul Sereno as "close to the root of the dinosaurs".[2] It is the earliest known definite theropod.
Eodromaeus was a relatively small dinosaur, with a total length of about 1.2 metres (3.9 ft) from nose to tail, and a weight of about 5 kilograms (11 lb). The trunk was long and slender. It is unknown how fast Eodromaeus could run: about 30 kilometres per hour (19 mph) has been suggested.[3] The animal was, like all early dinosaurs, bipedal. The forelimbs were much shorter than the hindlimbs, ending in hands with five digits. Digits IV and V were very reduced in size.[1]
