context_page_description: Patagotitan is a genus of titanosaurian sauropod dinosaur from the Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from multiple individuals: Patagotitan mayorum, first announced in 2014 and then validly named in 2017 by José Carballido, Diego Pol and colleagues. Contemporary studies estimated the length of the type specimen, a young adult, at 37 m with an approximate weight of 69 tonnes.
context_section_description: In 2017, Patagotitan was placed, within the Titanosauria, in the Eutitanosauria and more precisely the Lognkosauria, as a sister species of Argentinosaurus. Several subclades of the Titanosauria would have independently acquired a large body mass. One such event would have taken place at the base of the Notocolossus + Lognkosauria clade leading to a tripling of weight from maximal twenty to maximal sixty tonnes.
