Titanosaur
Titanosaurs (members of the group Titanosauria) were a diverse group of sauropod dinosaurs which included "Saltasaurus" and "Isisaurus". The titanosaurs were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the extinction event at the end of the Cretaceous. The group includes the largest land animals known to have existed, such as "Patagotitan"—estimated at long with a weight of —and the comparably sized "Argentinosaurus" and "Puertasaurus" from the same region. The group's name alludes to the mythological Titans of Ancient Greece, via the type genus (now considered a "nomen dubium)" "Titanosaurus". Together with the brachiosaurids and relatives, titanosaurs make up the larger clade Titanosauriformes.
