Megaraptor ("giant thief") was once thought to be the largest dromaeosaur ever found, but is now known to be a carnosaur related to Allosaurus. It lived in Late Cretaceous times in the Patagonian region of Argentina. It was a contemporary of Giganotosaurus, one of the largest carnivorous dinosaurs of all time.
Identification
Megaraptor was initially described as a giant dromaeosaur, known primarily from a single claw (about 1ft long) that resembled the sickle-shaped foot claw of dromaeosaurids. The discovery of a complete front limb, however, showed that this giant claw actually came from the first finger of a carnosaur's hand. The hand is still quite different from other carnosaurs, so it is not clear whether Megaraptor is an allosaurid, a carcharodontosaurid, a megalosauroid, or something else entirely.
It should be noted that, when first discovered and prior to publication, the spinosaurid Baryonyx was also reported to be a dromaeosaurid, again based on a large hand claw.
Size
Megaraptor's size is debated. However, most experts have come to agree that Megaraptor is approximately 8 meters (26 feet) in length and 3 meters (10 feet) in height.
