Article Synopsis
- The Carnian rocks of the Candelária Sequence in Southern Brazil contain some of the oldest dinosaur fossils, including a newly identified specimen, CAPPA/UFSM 0373.
- This well-preserved left ilium has been classified as belonging to the Herrerasauria group, showing anatomical similarities with dinosaurs previously found only in North America.
- The discovery suggests a previously unrecognized diversity of dinosaurs in these Carnian beds, indicating that even fragmentary specimens can provide valuable information about the history of dinosaurs.
Whereas ornithischian dinosaurs are well known from Jurassic and Cretaceous deposits, deciphering the origin and early evolution of the group remains one of the hardest challenges for palaeontologists. So far, there are no unequivocal records of ornithischians from Triassic beds. Here, we present an alternative evolutionary hypothesis that suggests consideration of traditional 'silesaurids' as a group of low-diversity clades representing a stem group leading to core ornithischians (i.
