An article published in the journal “Biology Letters” describes the discovery of a dinosaur of the sauropodomorph group that lived in today’s Brazil in the Late Triassic period, about 225 million years ago. Rodrigo Temp Müller and Sérgio Dias-da-Silva of the Universidade Federal de Santa Maria together with Max Cardoso Langer of the Universidade de São Paulo discovered an ancestor of the famous giant long-necked dinosaurs, which was named Macrocollum itaquii. It’s a useful discovery to clarify the evolution of that group of herbivorous dinosaurs.
