Comparison of the distal outlines of the left femora of a basal saurischian (a) and several non-sauropodan sauropodomorphs (b–d). aEoraptor (right femur reversed; based on Sereno et al. 2013). bPlateosaurus (right femur reversed; based on Huene 1926). cColoradisaurus (based on Apaldetti et al. 2013). dSchleitheimia. Abbreviations: ctf, crista tibiofibularis; le, lateral expansion, forming a posteriorly facing shelf lateral to the crista tibiofibularis on the distal femur in Plateosaurus and Coloradisaurus; mc, medial condyle. Arrows point to the flattened posteromedial surface of the crista tibiofibularis in the sauropodomorph taxa. Not to scale; drawn to the same distal width
