—Metatarsals I of PEFO 36741 and PEFO 44217 are proportionally long and slender metapodials and, as observed by the crushing of PEFO 34741, hollow. The proximal end of PEFO 34371 is twisted with respect to the distal end. In proximal view, the medial surface is nearly straight where it would articulate with metatarsal II, and the lateral edge is rounded, making a subtriangular proximal outline (

). The proximal outline is mediolaterally narrow, which indicates that the metatarsus was compact, not splayed (Ezcurra 2016:565-1). A compact metatarsus is present in ornithodirans and some early crocodylomorphs (Nesbitt 2011, Ezcurra 2016). The proximal surface of PEFO 36741 and PEFO 44217 is flat, would articulate with the distal tarsals, and would reach the proximal extent of metatarsal II, unlike in neotheropods where metatarsal I is more distally placed along the back of the metatarsus (Rauhut 2003, Nesbitt 2011:385-1). The distal end is asymmetrical, such that the medial condyle is more prominent than the lateral (
