About Patagotitan
Patagotitan is a genus of titanosaurian sauropod dinosaur from the Early Cretaceous (Albian stage) Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from at least six young adult individuals, Patagotitan mayorum, which was first announced in 2014 and then named in 2017 by José Carballido and colleagues. Originally thought to be the largest known titanosaur and land animal overall, preliminary studies and press releases suggested that Patagotitan had an estimated length of 37 m (121 ft) and an estimated weight of 69 tonnes (76 short tons). Later research revised the length estimate down to 31 m (102 ft) and weight estimates down to approximately 50–60 tonnes (55–66 short tons), suggesting that Patagotitan was of a similar size to, if not smaller than, its closest relatives Argentinosaurus and Puertasaurus. Still, Patagotitan is one of the best-known titanosaurs, and so its interrelationships with other titanosaurs have been relatively consistent in phylogenetic analyses. This led to its use in a re-definition of the group Colossosauria by Carballido and colleagues in 2022.
