Kryptops palaios is one of two newfound African dinosaurs announced on February 12, 2008.
The 25-foot-long (7.6-meter-long) species was likely a short-snouted animal with small, sharp teeth, tiny arms, and a horny face, which may helped the reptile in scavenging.
''With such a short snout and such puny arms, Kryptops would not be so well designed for grabbing something that was trying to run away,'' paleontologist Paul Sereno said.
Kryptops represents one of the earliest known abelisaurids, dinosaurs that were also found in South America and India, the researchers said.
