Unique skull features of this creature include pneumatized or ‘honeycombed' spaces, which allowed increased bone flexibility and compared to other members of Tetanurae, this animal possesses a more U-shaped jaw structure.
In 1994, Thomas Holtz argued that the enlarged metatarsal bones of this animal evolved in an evolutionary arms race since the same structure is also found in its smaller prey. Unique skull features of this creature include pneumatized or ‘honeycombed' spaces, which allowed increased bone flexibility and compared to other members of Tetanurae, this animal possesses a more U-shaped jaw structure. The earliest direct relative to this creature is the feathered Chinese Dilong and a recent debate concerns whether the "Nano" variety is a unique species or juvenile of this animal. Despite its prominent binocular vision consistent with predatory behavior, Jack Horner argues this creature is exclusively a (*) scavenger due to its large olfactory bulbs in an on-going debate. The largest and most complete specimen of this creature is displayed at the Chicago Field Museum and is named "Sue". Possessing a two- digit forelimb as opposed to the three of the earlier, Allosaurus, FTP, identify this large North American Late Cretaceous theropod dinosaur whose name translates from the Latin to "king of the tyrant lizards".
