Editing Dinosaur classification (section)

==Baron / Norman / Barrett classification==
In 2017 Matthew G. Baron and his colleagues published a new analysis proposing to put Theropoda (except Herrerasauridae) and Ornithischia within a group called Ornithoscelida (a name originally coined by [[Thomas Henry Huxley]] in 1870), redefining Saurischia to cover Sauropodomorpha and Herrerasauridae. Amongst other things this would require [[Hypercarnivore|hypercarnivory]] to have evolved independently for Theropoda and Herrerasauridae.<ref>
