Megaraptor

Megaraptor was a medium sized theropod from the Late Cretaceous Period. Its distinguishing feature was a large sickle shaped claw on each hand, which resemble the claws on the feet of dromaeosaurs. Because of this resemblance Megaraptor was originally described as a dromeosaur until a fossil hand found in 2002 proved otherwise, which proved that Megaraptor, in fact, a spinosaur-like dinosaur or an Allosaurus with a giant claw on their hands.

The current evidence suggests that the creature was a highly advanced and lightly-built allosauroid, and a member of the family Neovenatoridae. However, this statement is now invalid as more studies have suggested that Megaraptor and other megaraptorians are tyrannosauroids.

Warpath: Jurassic Park
The Megaraptor was featured in Warpath: Jurassic Park. As the game was made before the discovery of the aforementioned hand bone, it is portrayed as a giant dromeosaur; in this case, an enlarged/oversized Velociraptor. It was most likely chosen because the raptors from the movies were much too small compared to the other dinosaurs in the game. In the game's instruction manual it is codenamed M-Raptor, while in the game it is codenamed as Raptor. In the main menu, and the save settings/memory card menu, the Megaraptor took the Velociraptor's place (on the field with tall grass). It has three colors: tiger skin, brown, and black.
