Hey guys, it is time to rewrite what we know about dinosaur taxonomy now
these two days we have a potential huge change in dinosaur classification in American biology that may change the traditional dinosaur taxonomy completely: theropods and ornithischian dinosaurs are possibly belong to the same clade, ornithoscelida dinosaurs, while the primitive herrerasaurida dinosaurs and sauropods remains to the sauropod clade. As a result, tyrannosaurus rex may be closer to triceratops than titanosaurus instead of vice versa as the traditional thought.
