Diagnosis

Reference	Diagnosis
E. Hitchcock 1848 (Brontozoum)	Foot tridactylous, pachydactylous, tubercular-clawed; inner toe shortest; all of them directed forward. Phalangeal expansions on the inner toe, two; on the middle toe, three; on the outer toe, four; corresponding to the number of phalanges, except the distal expansion, which was probably made by the two extreme phalanges. Lower extremity of the tarso-metatarsal bone double-headed; rarely making a distinct impression through the cushion beneath. Cushion sloping upwards posteriorly. Claws on the lateral toes a little outside of their axes; on the middle toe, a little towards its inner side.
R. S. Lull 1915 (Gigandipus)	Those of the family, the most readily recognized being the small hallux which lies at right angles to digit II, instead of being rotated far to the rear as in Anchisauripus.
R. S. Lull 1915	Those of the family.
R. S. Lull 1915 (Hyphepus)	Bipedal, tetradactylous, hallux incumbent, curved sharply backward. Phalangeal pads obscurely defined; anterior digits apparently clawless.
H. Klein and S. G. Lucas 2021	Large (> 30 cm long), functionally tridactyl ichnite in which the digit III projection ratio is about 2.2, and the length-to-width ratio is about 1.4 to 1.5. Projection of digits II and IV along the axis of digit III about equal. Divarication of outer digits 30°-40°.
