Reappraisal of the Early Cretaceous sauropod dinosaur Amargatitanis macni (Apesteguía, 2007), from northwestern Patagonia, Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2016-09)
Amargatitanis macni Apesteguía, 2007 was described as a purported titanosaur sauropod. That referral is significant because Amargatitanis would represent one of the oldest known members of Titanosauria. However, this ...

(Academic Press Ltd - Elsevier Science Ltd, 2018-04)
A partially preserved sauropod natural cranial endocast (MLL-003) was collected from the Lower Cretaceous Mulichinco Formation in Argentina. The cast consists of cemented sandstone that has preserved in detail the general ...
A new dicraeosaurid sauropod from the Lower Cretaceous (Mulichinco Formation, Valanginian, Neuquén Basin) of Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2019-01)
A new dicraeosaurid sauropod, Pilmatueia faundezi gen. et sp. nov. from the Mulichinco Formation (Valanginian, Lower Cretaceous, Neuquén Basin, Argentina) is based on isolated skeletal remains collected from a single ...
