Temporal range: Upper Cretaceous, 98 mya
Megaraptor was a large 26 feet (8 m) long late Cretaceous dinosaur. It had two large sickle-like claws on each hand. It was a lightly built biped, with a large head and sharp, serrated teeth in powerful jaws.
The first fossil of Megaraptor to be discovered was one of its claws. As they strongly resembled the claws seen in Dromeosaurs, it was thought that Megaraptor was a large member of that family. Later, a complete hand was discovered, revealing the main claw was on its thumb.
