Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. Klein and S. G. Lucas 2021 | Small (up to 20 mm long) footprints of a quadruped with four and five digits on manus and pes, respectively. Pes plantigrade to semiplantigrade and length less than 20 mm long (typically 10-15 mm). Pes digits I to III closely grouped together with increasing length, digit IV longest and somewhat separate from the others; digit V set somewhat posterior and laterally directed. Manus semiplantigrade, smaller than pes; increasing lengths of digits from I to III, digit IV diverging outward from the grouping of I-III. Narrow quadrupedal trackways, common alternating manus-pes sets, small divergence of manus and pes axes, pace angulation rarely exceeds 90°. Tail/body drag may be present (based primarily on Gilmore, 1928; Haubold 1971b, 1996; and Melchor and Sarjeant, 2004). |
