| Critique | Romer (1956:621) coined the subfamily for an assemblage of genera including Euhelopus, Omeisaurus, Tienshanosaurus and the dubious tooth-form Chiayüsaurus. Later, 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). |
