Solving a dinosaurian puzzle: the identity of Aliwalia rex Galton. Adam M. Yates .Historical Biology: A Journal of Paleobiology, Issue: preview

Eucnemesaurus fortis Van Hoepen 1920 from the Late Triassic of South Africa is demonstrated to be the senior synonym of the puzzling dinosaur taxon Aliwalia rex Galton 1985. A new specimen of this poorly-known taxon is described. Eucnemesaurus is clearly a sauropodomorph and increases the diversity of sauropodomorph taxa in the South African Late Triassic to six. It shares a number of femoral synapomorphies with Riojasaurus from the Late Triassic of Argentina and Riojasauridae tax. nov. is erected to accommodate them. These
conclusions are supported by a comprehensive cladistic analysis of 46 sauropodomorph and other basal dinosauriform taxa using 353 osteological characters. This analysis also supports the paraphyletic nature of the traditional prosauropod assemblage.
