Riassunto / AbstractArgentinosaurus huinculensis gen. et sp. nov. is a giant titanosaur sauropod characterized by dorsal vertebrae with large hyposphene-hypantrum bearing extra articulations; bodies of sacral vertebrae 2-5 very reduced; hollow, cylindrical ribs; slender tibia 155 cm long. The family Andesauridae is proposed as a new rank to include Andesaurus, Argentinosaurus, and Epachthosaurus considering that the presence of hyposphene-hypantrum is a character not recorded in the Titanosauridae sensu Powell (1986). The systematics of the titanosaurs is briefly discussed and the new taxon Titanosauria is proposed to include the families Andesauridae and Titanosauridae.
