A new species of Triassic reptile from Brazil is a close cousin of a mysterious group called tanystropheids, according to a study by Tiane De-Oliviera of the Federal University of Santa Maria, Brazil and colleagues.
The best known sauropod dinosaurs were huge herbivorous creatures, whose brain structures were markedly different from those of their evolutionary predecessors, for the earliest representatives of the group were small, lithe carnivores.
