Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Y. Tsukiji et al. 2019 | Bipedal, with three functional pedal digits. The outer contours of digits II and IV diverge at low angle from the longitudinal axis of the ichnite. A distinct posterior impression is produced by a metatarsal-phalangeal pad. Interdigital webs link the proximal portions of the fleshy digital pads; the digits end in blunt claws or pointed hooves. The ichnite is almost as wide as, or wider than, it is long. |
