New 20-Meter Brazilian Dinosaur 'Dasosaurus' Shows How Sauropods Crossed Between Europe and South America

A new species of long-necked sauropod, named Dasosaurus tocantinensis, has been formally described from fossils unearthed in 2021 during road and rail construction near Davinópolis in Maranhão state, northeastern Brazil. Published on May 15 in the Journal of Systematic Palaeontology, the study by Elver L. Mayer and colleagues identifies the animal as a roughly 20-meter-long member of the Somphospondyli — and surprisingly, its closest known relative is the Spanish dinosaur Garumbatitan. The match implies that Early Cretaceous sauropods were still moving between continents long after the Atlantic had begun to widen.
