Scientists discover a new dinosaur from Argentina with a crocodile bone in its mouth

Scientists discovered a new Argentina dinosaur who could have used his long arms and claws to capture prey. The new discovery was perhaps 23 feet long and was from a mysterious group of dinosaurs called Megaraptorans. Most predator fossils are fragments. In a new study, the researchers say they discovered part of a skull as well as bones of arms, legs and tail of rocky formation in Argentina. Discovery could help scientists understand how these creatures have nourished and where they come across the evolutionary chronology. Research was published Tuesday in the journal Nature Communications.
