Researchers from the Federal University of Santa Maria (UFSM) discovered the fossil skull of a reptile that lived approximately 230 million years ago,belonginf to the order Rhtnchosauria in Agudo, a municipality of Rio Grande do Sul, the southernomost state of Brazil, known for its lush nature among hills and waterfalls, a strong legacy of German immigration and Gaucho culture, ecotourism potential, highlighted by the the Raddatz Waterfall, Morro Agudo, and pasleonthological tourism in the Espaço dos Dinos.
This newly identified rhyncosaur species from Brazil’s Late Triassic is a 1.2 to 1.5 metre - long herbivore featuring a triangular head, parrot - like beak, specialized teeth for cutting plants and digging for roots, and strong similarities to Scottish rhynchosaurs.
Evolutionary analysis revealed that this new species has close relatives found in Scotland, which is explained by the fact that in the Triassic period the continents were still united in the supercontinent Pangaea, allowing similar species to be distributed over large areas.
The study describes the species called Isodapedon varzealis, a quadrupedal herbivorous reptile belongs the order Rynchosauriat a group of extinct herbivorous, Triassic archosauromorph reptiles that existed before the expansion of the dominant dinosaurs, according to information from Metrópoles, a Brazilian online newspaper based in Brasilia.
Rhyncosaurs usually have teeth that form plates divided by a slit with asymmetrical shapes, but in this reptile discovered in Agudo those plates have more balanced proportions, hence their name Isodapedon, which means “equal dental plates”.
With this finding, Brazil now has six known Triassic rhynchosaurs, and the researchers believe that this diversity could be the result of different feeding strategies that reduced competition between species.
The fossil is now part of the collection of the Center for Support of Palaleontological Research of the Fourth Colony, in São João do Polêsine, a municipality in the state of Rio Grande do Sul.
