Dasosaurus is an extinct genus of somphospondylan sauropod dinosaur known from the Early Cretaceous (Aptian) Itapecuru Formation of Brazil. The genus contains a single species, Dasosaurus tocantinensis. Its morphology is similar to the titanosauriform Garumbatitan, known from the Early Cretaceous of Spain.

A New Sauropod Dinosaur from the Early Cretaceous of Brazil
Brazil Cretaceous Early Cretaceous Dasosaurus Dinosauria
A new genus of sauropod dinosaur has been named from Brazil.  It expands the known diversity of Early Cretaceous sauropods in the northern part of South America. In addition, the newly named dinosaur Dasosaurus tocantinensis provides fresh evidence of dinosaur dispersal between Europe, Africa and South America. The scientific paper describing the new taxon was
