New Dicynodont Taxon Could Transform the Timeline of Dinosaur Origins

Scientists have described a new species of dicynodont from fossils discovered in Tanzania. These fossils could help palaeontologists refine the timeline for the origin of the dinosaurs. The new species has been named Dinodontosaurus isiyavamanda. It lived around 240 million years ago during the Triassic Period. Importantly, Dinodontosaurus was not a dinosaur.

240-million-year-old reptile fossil reveals a lost chapter before dinosaurs and crocodiles

A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles. The small predator had unusually positioned legs that may have allowed it to move more efficiently than many earlier reptiles. Its close relatives were previously known mostly from other continents, suggesting these ancient animals spread much farther across the Triassic world than scientists realized.
