Diagnosis
ReferenceDiagnosis
R. A. Thulborn and M. Wade 1984(ichnogenus and ichnospecies): narrow trackway of small to medium-size digitigrade biped, with pace angulation about 160°. Footprint size index (SI) usually between 3.2 and 11.1 cm, but occasionally as high as 26.6 cm. No imprints of hand or tail. Footprints tridactyl (digits 2, 3 and 4), slightly broader than long (ratio FW/FL about 1.15), showing distinct positive rotation. Digits broad, with rounded or bluntly angular tips,without indications of phalangeal pads. Digit 3 longest, with sub-parallel sides. Digit 4 shorter and slightly narrower than digit 3, extended as blunt posterior salient. Digits 3 and 4 close together, parallel or only slightly divergent. Digit 2 shortest, and widely separated from digit 3 (with interdigital angle often about 60°). Imprints of digits 2 and 3 sometimes completely separated. Posterior margin of foot convex forwards. Ratio PL/FL usually between 8.0 and 13.5, rarely as low as 4.0 or as high as 15.0; ratio SL/FL usually between 16.0 and 24.0, rarely as low as 8.0 or as high as 27.0
