Achillobator giganticus

A rather large dromaeosaurid, one of the largest known as a matter of fact.  It is believed to achieve a maximum length of 5-6 meters (16.5 - 19.7 ft), nearly the size of it's close cousin Utahraptor.  It is known from the Turonian epoch of the Late Cretaceous, and remains of the animal have been uncovered in Mongolia.  Here, it is seen feeding on the carcass of an Enigmosaurus mongoliensis.
