Epachthosaurus is one of the giant titanosaurs of South America. These huge plant-eaters, the last of the long-necked sauropod dinosaurs, spread from South America through the rest of the world in the last part of the Cretaceous period.

Unlike the other titanosaurs, Epachthosaurus appears to have lacked dermal plates. Very little material is known from this dinosaur, primarily vertebrae and parts of the hip.
