Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. H. Colbert and D. Merrilees 1967 | Bipedal trackway, with pace angulation about 140°-160°, stride about 2 meters
at a normal walk. Individual impressions large (order of 325 millimetres in length), three-toed, and with the angulation of the digits showing an average of about 35° to 45°. Each impression showing second, third and fourth digits with phalangeal formulae of 3 for digit II, 4 for digit III and 5 for digit IV. Trackways probably those of a megalosaurian carnosaur. |
