A Late Triassic dinosauriform from south Brazil and the origin of the ornithischian predentary bone
@article{Ferigolo2007ALT, title={A Late Triassic dinosauriform from south Brazil and the origin of the ornithischian predentary bone}, author={Jorge Ferigolo and Max Cardoso Langer}, journal={Historical Biology}, year={2007}, volume={19}, pages={23 - 33} }
The South American Late Triassic offers the most comprehensive window to the early radiation of dinosaurs. This is enhanced by the discovery of Sacisaurus agudoensis, a new dinosauriform from the Caturrita Formation of Brazil. Various morphological features suggest its close phylogenetic affinity to Silesaurus, and both may be basal ornithischian dinosaurs. Sacisaurus has a pair of elements forming the tip of its lower jaw, hypothesized to be equivalent to the ornithischian predentary. This…

The analysis suggests that the dentition and diet of silesaurids, ornithischians and sauropodomorphs evolved independently from a plesiomorphic carnivorous form, and Asilisaurus demonstrates the antiquity of both Ornithodira and the dinosaurian lineage.
The origin and early evolution of dinosaurs
- Geography, Environmental ScienceBiological reviews of the Cambridge Philosophical Society
- 2010
The oldest unequivocal records of Dinosauria were unearthed from Late Triassic rocks accumulated over extensional rift basins in southwestern Pangea, and the group achieved a nearly global distribution by the latest Triassic, especially with the radiation of saurischian groups such as “prosauropods” and coelophysoids.
