The tibia of "Protoavis" allegedly possesses both a lateral and cranial cnemial crest, though the validity of this claim is subject to question due to the preservation quality of the material. The fibula is continuous to the astragalocalcaneal unit. A tibiotarsus is absent, unusual considering Chatterjee's claims for the pygostylian affinity of "Protoavis", as is a tarsometatarsus. The ascending process of the astragalus is reduced, a character entirely incongruous with a highly derived status for "Protoavis". Curiously, such abbreviation of the ascending process is found in ceratosaurs, and in its general osteology, the "Protoavis" tarsus and pes, is quite similar to those of non-tetanuran theropods. Chatterjee's restoration of the hallux as reversed is nothing more than speculation, as the original spatial relationships of the pedal elements are impossible to ascertain at this time.
