Megaraptor was a large, meat-eating dinosaur with a long, sickle-shaped claw on each foot. This fast-running predator lived during the late Cretaceous period, about 90-84 million years ago.

Anatomy: The second toe on each foot had a 14-inch (35 cm) sickle-like claw, and the other toes had smaller claws. When alive, this claw would have been sheathed in a horny, keratinous material much like our fingernails, making the claw even bigger, longer and sharper. The long tail was used for balance and for fast turning ability. It had a relatively large brain and large, keen eyes. Megaraptor was about 20-26 feet (6-8 m) long.

Name: Paleontologist F. Novas named Megaraptor in 1998 (when it was still thought to be a raptor). Megaraptor was more primitive than the Dromaeosaurids (the true raptors), which had wider feet.

Fossils: Incomplete Megaraptor remains were found in 1996 in Northwest Patagonia, Argentina, by paleontologist F. Novas. Fossils included a huge sickle-shaped claw, metatarsal, ulna, and a finger bone. No skull has been found.
