It is the part of the pentadactyl limb that includes the metatarsals and digits (phalanges). Both second metatarsals are preserved and only the left fourth metatarsal is preserved. The second metatarsal of the foot is wider than the other metatarsals. The metatarsals are analogous to the metacarpal bones of the hand. It had stock metatarsals and a prominent left fibula measuring . The foot has three digits, metatarsals with toes. The three muscles originate on the medial aspect of metatarsals III-V. The tubercles of the metatarsals are large. The metatarsals (foot bones) were spaced closely, but not fused together. Kangaroo rats have large hind feet with long metatarsals and no first digits. The five metatarsals (foot bones) were thin, elongated, and close together. This is a common problem that can affect the joints and bones of the metatarsals. All the metatarsals had strongly developed ginglymoidal joints. The central metatarsals are fused for a small distance. The bird foot also contains one or two metatarsals not fused in the tarsometatarsus.
