Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. F. Bonaparte 1986 | Allosaurid with deep depressions between the basioccipital condyle and the opisthotic process; braincase similar to that of Eustreptospondylus but with more pronounced lateral basisphenoid depressions and alar process of the laterosphenoid. Most postcranial characters comparable to those of Allosaurus, but with a shorter scapula and a coracoid not expanded but subcircular. Pubis with an obturator foramen totally enclosed by an bony lamina and forming a modest neck; ischium less reduced ventrally than that of Allosaurus. Ulna, tibia and femur more slender than in Allosaurus, but proportionally a little more massive than in Dilophosaurus. (Translated by M. Carrano.) | |
| M. T. Carrano et al. 2012 | Tetanuran with: (1) strongly inflated base of maxillary ascending process (Rauhut 2003); and (2) evenly rounded ventral surfaces of most sacral centra, except sacral 3 bears flat midline strip and sacral 5 is broad and flat (Benson 2010a). |
