- Notes: Only a pair of arms belonging to Deinocheirus have been discovered in southern Mongolia. These arms were very long -- 8 feet (2.4 meters) -- and their hands accounted for 2 feet (0.6 meters)of the length. The three fingered hands were equipped with formidable,8 - 11 inch (20 - 30 cm), hook-like claws. Deinocheirus may haveused these spectacular claws to attack and kill prey, but it has also beensuggested that it used them for climbing trees. Some scientists believethat Deinocheirus may be a large Ornithomimosaur.
