- •
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
