In Depth

       Chubutisaurus seems to have been a large but primitive titanosaur that lived in Chubut Province towards the end of the early Cretaceous,‭ ‬hence the name which means‭ ‘‬Chubut lizard‭’‬.‭ ‬Although known from different members of the Cerro barcino Formation,‭ ‬possible predatory threats to Chubutisaurus might have included large theropod dinosaurs such as Genyodectes as well as‭ ‬the‭ ‬large Tyrannotitan.
