Newly Discovered Dinosaur Has Short Arms Like The T. Rex

The Tyrannosaurus rex, and other members of the tyrannosaurus family, are not the only carnivorous dinosaur to have tiny arms, according to a study recently published in Current Biology. Researchers from Ernesto Bachmann Paleontological Museum in Neuquén, Argentina, discovered fossilized remains of the Meraxes gigas, a large carnivore — like the T. rex — that also had disproportionate arms. These findings indicated that the T. rex and M. gigas evolved independent of each other and the use of these shorter arms.
