| Reference | Diagnosis | |
|---|---|---|
| O. Mateus et al. 2006 | Like other species of Allosaurus except for: jugal participation in the antorbital fenestra; maxilla forked posteriorly; truncated ventroposterior process of the maxilla; nasal with two pneumatic foramina (the anterior foramen twice the size of the posterior); posteroventral projection of the jugal more than twice the posterodorsal projection; large anterior surangular foramen; no lacrimal-maxillary contact; squamosal contacts the quadratojugal by a sigmoidal suture; squamosal projects ventrally into laterotemporal fenestra; lacrimal horn narrow in lateral view; large ventral projection of postorbital; rugose dorsal rim of the nasal; the occipital condyles above the squamosal-quadratojugal contact; the anterior tip of quadratojugal is anterior to the laterotemporal fenestra; the lateral lamina of lacrimal is subtle; palatine contacts the pterygoid dorsoposteventral tip of the ostorbital reaches the lower rim of the orbit. |
