Basal dinosauromorphs
Research
- Marsicano et al. (2016) date the Chañares Formation, containing fossils of non-dinosaurian dinosauromorphs Lagerpeton, Lewisuchus, Marasuchus and Pseudolagosuchus, to early Carnian (236–234 Ma), 5–10 million years younger than previously thought. On this basis the authors postulate that the origin of dinosaurs was a relatively rapid event, as the transition from vertebrate communities containing only non-dinosaurian dinosauromorphs to communities containing the first dinosaurs occurred in less than a 5-million year interval.[56]
