Diagnosis

Reference	Diagnosis
R. S. Lull 1904	Bipedal, tetradactylous; hallux rotated to the rear so as to lie in lin with the claw of the second digit, insistent, that is, inserted high on the leg so that only the tip of the claw impresses and that only when the weight is borne on the hinder part of the foot. The hallux evidently bore a well developed, subfunctional, grasping claw. Foot of moderate size with well marked phalangeal pads. Limbs of medium length. Manus and tail never impressing.
R. S. Lull 1915	Those of the family.
H. Klein and S. G. Lucas 2021	Medium-sized (~ 20 cm long), functionally tridactyl ichnite in which the digit III projection ratio averages about 1.4, and the length-to-width ratio is about 2.0. Digit II tends to project more than IV along the axis of digit III. Divarication of outer digits averages 27°.
