Dryptosaurus is a genus of tyrannosauroid that lived approximately 67 million years ago during the late Cretaceous period in what is now New Jersey. Dryptosaurus was a large, bipedal, ground-dwelling carnivore, that grow up to 7.5 m long and weigh up to 1.5 t. Dryptosaurus seems to have had relatively long arms when compared with more derived tyrannosaurs. Its hands, which are also relatively large were believed to have had three fingers.
