sauropodomorpha การใช้

The Sauropodomorpha is split into Prosauropoda and Sauropoda.
Sauropodomorpha, of which Neosauropoda is a subclade, first arose in the late Triassic.
The ornithischia and sauropodomorpha are both.
Setting aside the basal Saurischia, the rest of the Saurischia are split into the Sauropodomorpha and Theropoda.
Basal members of Sauropodomorpha are often collectively termed paraphyletic group, the exact phylogeny of which has not been conclusively determined.
