Diagnosis
ReferenceDiagnosis
C. I. Serrano-Brañas et al. 2016An ornithomimid dinosaur that possesses the following characteristics: a very distinctively articulation between metatarsals, where the distal ends of metatarsals II and IV contact directly with the distal facet of metatarsal III; a metatarsal III with a weakly ginglymoid distal articular facet that bears some pits and deep longitudinal scars; also, the medial and lateral sides of this element are shaped in the form of metatarsals II and IV, so all distal ends fit together when they articulate; an asymmetrical and narrow pedal ungual with shallow grooves in both medial and lateral sides; it also possesses a ventromedial edge with a deep sulcus close to the articular end and ventrolateral edge with a prominent keel; finally, the ventral surface of this element do not has a flexor tubercle, instead it is weakly concave and contains small foramina.
