Megaraptor namunhuaiquii was a fairly large predatory dinosaur that hunted in South America during the Late Cretaceous Period, between 91 and 88 million years ago. When paleontologists first discovered its fossilized talons in the 1990s, they interpreted them as coming from a giant dromaeosaurid related to the infamous Velociraptor and Deinonychus. However, subsequent discoveries would reveal that the enlarged talons were positioned on the dinosaur’s fingers instead of its toes as on the dromaeosaurids. Most likely, Megaraptor and its kin were most closely related either to the tyrannosaurs or to the allosaurs.
