A third finger has become so reduced that it is just a tiny bone in the flesh of the animal’s hand. “It’s really cool that the arms of this particular dinosaur are reduced down to basically two fingers like we see in another very famous well-adapted predator that we know of as Tyrannosaurus rex,” says Dr.
What kind of dinosaur has 3 fingers?
In northeastern Montana’s Hell Creek formation, a Tyrannosaurus rex has been unearthed with three fingers on each hand. The existence of digit III had previously surmised because of a joint surface on the ulnar aspect of the base of metacarpal II.
Most theropods were three-fingered, having lost all remnants of the fourth and fifth fingers. Tyrannosaurids (including Albertosaurus, Daspletosaurus, Tarbosaurus, and Tyrannosaurus) were notable for their two-fingered hands and unusually short arms; they had lost the third finger.
