Gondwanatitan (meaning "giant from Gondwana") was a titanosaurian sauropod dinosaur. Gondwanatitan was found in Brazil, at the time part of the southern supercontinent Gondwana (also called gondwanaland), in the late Cretaceous Period (70 mya). Like some other sauropods, Gondwanatitan was tall and ate tough shoots and leaves off of the tops of trees. G. faustoi's closest relative was Aeolosaurus.
The type species is Gondwanatitan faustoi, formally described by Kellner and de Azevedo in 1999.
The vertebrae from the middle part of its tail had elongated centra.[1] Gondwanatitan had vertebral lateral fossae that resembled shallow depressions.[2] Fossae that similarly resemble shallow depressions are known from Saltasaurus, Alamosaurus, Malawisaurus, and Aeolosaurus.[2] Venenosaurus also had depression-like fossae, but its "depressions" penetrated deeper into the vertebrae, were divided into two chambers, and extend farther into the vertebral columns.[2]
Its middle tail vertebrae's neural spines angled anteriorly when the vertebrae are aligned.[3] These vertebrae resemble those of Cedarosaurus, Venenosaurus, and Aeolosaurus.[3]
