The taxon includes some of the smallest known adult non-avian theropod specimens, with the holotype specimen measuring only in length, including the tail.

Allosaurus
In 1991 "Big Al" (MOR 693), a 95% complete, partially articulated specimen of "Allosaurus" was discovered. It measured about 8 meters (about 26 ft) in length. MOR 693 was excavated near Shell, Wyoming, by a joint Museum of the Rockies and University of Wyoming Geological Museum team. This skeleton was discovered by a Swiss team, led by Kirby Siber. In 1996 the same team discovered a second "Allosaurus", "Big Al Two", which is the best preserved skeleton of its kind to date.
