       An early Cretaceous titanosaur from South America,‭ ‬the precise size of Amargatitanis is hard to establish due to lack of remains.‭ ‬The name Amargatitanis is a reference to its discovery in the La Amarga Formation,‭ ‬and its titanosaurian lineage.‭ ‬Other sauropods known from the La Amarga Formation include Zapalasaurus and the similarly named Amargasaurus,‭ ‬though as diplodocids they would not have been closely related to Amargatitanis.‭ ‬The abelisauroid theropod Ligabueino is also known from this formation.
