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 dromeosaurs. Because of this resemblance Megaraptor was originally described as a dromeosaur until a fossil hand found in 2002 proved otherwise. The current evidence suggests that the creature was a highly advanced and lightly-built allosauroid.

Jurassic Park inspired games
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. It was most likely chosen because the raptors from the movies were to small compared to the other dinosaurs of the game.
