Thedifference between slender and broad feet is not growth related since thereare small prosauropods with broad feet (Figs 7B, 8A-C, H). These appear tobe juveniles of species that grew much larger (Figs 7B, H, K, 8H, O-P —allAmmosaurus major, see Galton 1971) and all the larger prosauropods arebroad-footed. The prosauropod families Plateosauridae (Figs 7-8) and Melano-rosauridae (see Bonaparte 1972a: figs 62, 70; Raath 1972: figs 9f, lOa-b) areall broad-footed, whereas the Anchisauridae as currently classified includeboth slender and broad-footed forms (Figs 7-8).
