  1. The classic model of Dinosaur evolution has two primary lineages. The Ornithischians and the Saurischians (Theropods and Sauropods). This model has been challenged by a model in which Ornithischians and Theropods fall under the clade Ornithoscelida, while Saurischia would include Sauropods and Herrerasauridae. This, would explain why feathers have been found in Ornithischian lineages as well as Theropods while no feathers have ever been discovered on any Sauropods. HOWEVER... Pterosaurs, which had diverged earlier, had feathers (I'm referring to monofilaments as feathers in this context), which might nullify that entire point, because the the potential to grow feathers is common throughout Ornithodira. Does anyone else have any thoughts on which model they prefer, or which one is more supported?
