Critique
Romer (1956:621) coined the subfamily for an assemblage of genera including Euhelopus, Omeisaurus, Tienshanosaurus and the dubious tooth-form Chiayüsaurus. Upchurch (1995:373) coined the family to include a group of Chinese sauropods (Euhelopus, Shunosaurus, Omeisaurus and Mamenchisaurus) that are now believed to be phylogenetically disparate (Wilson and Sereno 1998). Upchurch et al. (2004), in a new cladistic analysis, corroborated the hypothesis of Wilson and Sereno (1998), disbanding Upchurch’s (1995) clade of Chinese sauropods.
