Diagnosis
Reference | Diagnosis | |
---|---|---|
M. G. Lockley 2000 (Bueckeburgichnus) | Large tetradactyl theropod track with small hallux (digit I). Digit II wide and well-padded. Digit III parallel sided proximally but strongly tapering distally. Digit IV narrow with traces of discrete digital pads. | |
N. L. Razzolini et al. 2017 | large (length>40 cm to a maximum of 80 cm), elongate
(average length:width ratio 1:2), asymmetric tridactyl tracks; clear pad impressions that match the typical theropod phalangeal formula (2:3:4 corresponding to digits II, III and IV); sigmoidal impression of digit III; ungueal impression of digit I oriented posteriorly and medially; large impression of the metatarsal phalangeal pad of digits II and III and average divarication angle between digit II-III of 40 ̊,and between digits III-IV of 30 ̊. Trackway show irregular track morphology, with variable steps length and pace angulation; prominent inward rotation with respect to the trackway midline of the distal end of digit III. |
