Resumen:
A new basal sauropod titanosaur, Kaijutitan maui ge et sp nov is described. The holotype of this species, which comes from the Sierra Barrosa Formation (upper Coniacian, Upper Cretaceous) consists of cranial, axial and appendicular elements presenting an unique combination of plesiomorphic and apomorphic characters. The most notable characteristic observed in Kaijutitan is the presence of anterior cervical vertebrae with bifid neural spines, a condition that would have evolved several times among sauropods.The phylogenetic analysis places Kaijutitan as a basal titanosaur, the sister taxon of Epachthosaurus + Eutitanosauria. The new species supports the coexistence, in the Late Creteceous (Turonian-Santonian) of basal titanosaurs and eutitanosaurs sauropods, at least in Patagonia.
