(Yates et al. 2010; Fig. 1) was originally considered a basal sauropodomodph dinosaur, because it is one.
In the large reptile tree (LRT, 1760+ taxa; subset Fig. 2) Early Jurassic Aardonyx nests with the Late Jurassic prosauropod, Saturnalia, a taxon not mentioned in the Yates et al. paper. Aardonyx is larger, more robust and has shorter feet, as in sauropods, making it a sauropod mimic.. so, not in the lineage of sauropods. That should be relatively uncontroversial.
