Hey guys, sorry I haven't been active in a while. But I'm just really surprised by this news: apparently Dinosauria needs some revision now. A new study has erected a new group for dinosaurs called Ornithoscelida, which includes all ornithischians and theropods. Saurischia still exists, but now includes just the sauropodomorphs and herrerasaurids. Basically, what this means is that theropod dinosaurs are no longer part of Saurischia, and Ornithischia might not exist anymore
I actually don't know what to think about this, and honestly, I'm not jumping the bandwagon yet. I'm pretty sure some paleontologists are going to write a counterargume
