       Named after the famous palaeontologist José Fernando Bonaparte for his contributions to the advancement of palaeontology,‭ ‬Bonatitan seems to have actually been quite a small titanosaur.‭ ‬Hailing from the Allen Formation,‭ ‬Bonatitan likely shared its habitat with other dinosaurs such as other titanosaurs like Saltasaurus,‭ ‬Laplatasaurus,‭ ‬Aeolosaurus and Rocasaurus and the hadrosaurs Lapampasaurus and Willinakaqe.‭ ‬Predatory threats may have come from theropod dinosaurs such as Austroraptor.‭ ‬Large numbers of fish and turtle fossils are also known indicating the presence of a lot of water in the ecosystem of Bonatitian while the pterosaur Aerotitan is also known to have been present.
