South American titanosaurians have been central to the study of the evolution of Cretaceous
sauropod dinosaurs. Despite their remarkable diversity, the fragmentary condition of several …

After the extinction of rebbachisaurids during the Cenomanian–Turonian interval,
titanosaurs were the only group of sauropods to face the K–Pg event. This same global …

Although dinosaurian ichnofaunas are common in the Northeastern Brazilian Interior Basins,
osteological remains are poorly represented in these areas. One of the main challenges in …

The titanosaur sauropod record of Patagonia, mainly recovered from Upper Cretaceous
strata, is probably the richest worldwide. Here we present a new sauropod dinosaur …

Titanosaurian sauropods were the most diverse and successful group of large-bodied
terrestrial herbivores. Two aspects regarding their evolutionary history stand out, namely …

Titanosaurian dinosaurs include some of the largest land-living animals that ever existed,
and most were discovered in Cretaceous deposits of Argentina. Here we describe the first …

Here we describe a new record of a sauropod dinosaur from the Lower Cretaceous
(Hauterivian–Barremian) Rio Piranhas Formation, Sousa Basin, NE Brazil. Dinosaur fossil …

In the Neuquén Basin, the Portezuelo Formation (Turonian-Coniacian, Upper Cretaceous) is
represented by extended fluvial outcrops that are well-known for yielding an abundant and …

The fossil record of cranial material from titanosaurid sauropods is very poor and no
complete skull has been described so far. Here we describe a new braincase (MUCPv-334) …

Partial remains of a titanosaur sauropod collected in the Tolar Formation (Upper
Cretaceous) at the Atacama Desert (Antofagasta Region), northern Chile, is described, and …
