As indicated by Walker (1964: 107), this last character- state does not necessarily imply a taxonomic or phylogenetic affinity between Herrera- saurus and the Upper Jurassic and Creta- ceous true carnosaurs, and the genus must be placed in the Palaeopoda either as a member of the Gryponychidae or as a separate line. The other palaeopodan genus is Ischisaurus, known from incomplete remains of different individuals. It is the- codontosaurid-like in size and general ap- pearance, and the small size of the humerus, which hardly exceeds half of the length of the femur, suggests that it was a definitely bipedal form. A supposed Brazilian dinosaur has been described by von Huene as Spondylosoma, on the basis of isolated bones insufficient to allow of even ordinal assignment. Ma- terial recovered later, and being at present studied by Colbert, clearly indicates, how- ever, that a saurischian of palaeopodian. 0 1 2 3 4 S c.
