Zoology: Bones (Fossil / Prehistoric)

From the Nemegt Formation of the Gobi Desert in Mongolia, this claw is from the Mongolian equivalent of the T. rex. Found in 2002 the rare Tarbosaurus was probably a young adult about 30 feet long. About 70 million years old, some say it is so closely related that it should be placed in the same genus as T. rex (Tyrannosaurus).
