Diagnosis
ReferenceDiagnosis
H. Klein and S. G. Lucas 2021Chirotheriid trackways of a quadruped with plantigrade to semidigitigrade posture of the pes and manus. Pentadactyl pes imprint with rounded to oval shape and broad plantar surface. Pedal digit group I–IV nearly as wide as long and with an overall divarication of more than 40°. Digits moderately spread, relatively short and broad with robust, rounded pads and narrow claws, digits III and II longest, digit IV always preserved. Pedal digit V lacks a separated phalangeal segment or shows an indistinct trace of it, which is anteriorly oriented, but never recurved. In comparison with the pes, the manus imprint is much smaller, and manual digit group I–IV is mostly wider than long, but otherwise of a shape similar to the pes. Trackways with narrow pattern and relatively high pace angulation (160°), moderate outward rotation of the pes and stronger outward rotation of the manus.
