Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| X.-C. Wu et al. 2009 | A medium to large-sized theropod that differs from other tetanurans with the following combination of characters: supraoccipital excluded from the foramen magnum by exoccipitals; paroccipital process down turned slightly (approximately 110 degrees from vertical); axis with a large, sharply pointed epipophysis and a thin lamina between the epipophysis and neural spine that is broader than in other theropods where it is present; anteroventral to dorsoposterior pubic length is almost the same as the height of the iliac blade; lacks a ventral notch distal to the obturator process on the ischiuml and has an ischium that is relatively long (more than 96% the length of the pubis). |
