About This File
Stokesosaurus ("Stokes' lizard") was a small early tyrannosaur from the Late Jurassic period of Utah.
It was named after Utah geologist William Lee Stokes.
The holotype consists of a hip bone, originally thought to belong to the possible early
tyrannosaur Iliosuchus (Galton, 1976), as well as several vertebrae and a partial
braincase (Chure and Madsen, 1998). Another illium referred to this dinosaur (Foster and
Chure, 2000) is lost but may actually belong to the related Aviatyrannis, and a premaxilla
thought to belong to Illiosuchus (Madsen, 1974) is actually from Tanycolagreus.
Stokesosaurus and Tanycolagreus are about the same size, and it is possible that the
latter is a junior synonym of the former. However, the ilium (the best known element of
Stokesosaurus) of Tanycolagreus has never been recovered, making direct comparison
difficult.
