Megaraptor Fossils: Hunters of History

Discovery and Significance

The first Megaraptor fossil was discovered in Argentina in 1996. It was a partial skeleton, including the skull, vertebrae, and limbs. This discovery was significant because it represented a new type of theropod dinosaur, one that was larger and more powerful than previously known.

Physical Characteristics

Megaraptor was a large theropod dinosaur, measuring up to 30 feet long and weighing up to 2 tons. It had a long, slender body with a powerful tail. Its skull was large and robust, with a deep snout and sharp teeth. Megaraptor‘s arms were long and muscular, with large claws on its hands.
