A paper which, unsurprisingly, is still being hotly debated.Shoopwoop17 wrote: ↑Tue Dec 01, 2020 6:09 amTechnically yes, but that is not where the name comes from. Ornithoscelida is a clade which includes theropods and ornithischians but not sauropodomorphs or herrerasauridae. Dinosaurs are traditionally split into ornithischia and saurischia, but a recent paper suggested that this grouping may not be correct, and that theropods are more closely related to ornithischians than sauropods.
Personally I'm waiting for more studies to confirm or dismiss the notion, but I've always thought it curious that the bird hips that give ornithischians their name are also possessed by many theropods and, you know, actual birds, but the two groups were only distantly related.
