Scientists discover a new dinosaur from Argentina with a crocodile bone in its mouth Updated 30 mins ago Scientists have discovered a new dinosaur from Argentina that may have used its long arms and claws to capture prey. The new find was possibly 23 feet long and hailed from a mysterious group of dinosaurs called megaraptorans. Most of the fossils of the predator are fragments. In a new study, researchers say they uncovered part of a skull as well as arm, leg and tail bones from a rock formation in Argentina. The discovery could help scientists understand how these creatures fed and where they fall on the evolutionary timeline. The research was published Tuesday in the journal Nature Communications.
