文摘

•: Cretaceous-aged dome-headed dinosaurs are convergent with Triassic-aged Triopticus
•: Archosauromorph reptiles evolved extreme body plans after the end-Permian extinction
•: Dinosaurs repeated body plans present in their Triassic-aged relatives
•: The early evolution of body plans may constrain later body plans in the same group
