Diagnosis
ReferenceDiagnosis
F. E. Peabody 1948Long-striding, sometimes semi-bipedal trackways of a small pentadactyl reptile. The manus is always closer to the midline and is always overstepped even in the walking gait by the much larger pes in a moderately narrow trackway pattern; pace angulation (pes) as high as 146 degrees in a running trackway and as low as 93 degrees in a walking trackway. The pes impression indicates a foot with an advanced digitigrade posture and with a strongly developed but slender digit V rotated to the rear where it functioned as a prop. Manus digit V mayor may not be rotated backward but it has a propping function. Digit IV on both manus and pes is longer than III; digit I may fail to impress; claws are evident on digits I-IV. Scaly plantar surface, rarely shown, is charac­terized by transversely elongate scales on the digit axis bordered by granular scales.
