The First Giant Titanosaurian Sauropod from the Upper Cretaceous of North America

  title={The First Giant Titanosaurian Sauropod from the Upper Cretaceous of North America},
  author={Denver Warwick Fowler and Robert Miles Sullivan},
Argentinosaurus (Cenomanian, Argentina) is generally accepted as being the largest dinosaur so far discovered and is one of several giant titanosaurian sauropods known from the Upper Cretaceous of South America and Asia, but surprisingly not from North America. Here we present the first evidence of giant titanosaurian sauropods from the Upper Cretaceous of North America: two enormous vertebrae and a partial femur, from the Naashoibito Member of the Ojo Alamo Formation, New Mexico, and referred… Expand

A Sauropod Dinosaur Pes from the Latest Cretaceous of North America and the Validity of Alamosaurus sanjuanensis (Sauropoda, Titanosauria)
ABSTRACT Complete sauropod pedes are rare in the fossil record, which has limited their use in systematics. We describe a nearly complete, large sauropod pes from the Maastrichtian-age NaashoibitoExpand
A New Giant Titanosauria (Dinosauria: Sauropoda) from the Late Cretaceous Bauru Group, Brazil
The phylogenetic analysis presented here reveals that Austroposeidon magnificus is the sister group of the Lognkosauria, and CT scans reveal some new osteological internal features in the cervical vertebrae such as the intercalation of dense growth rings with camellae, reported for the first time in sauropods.

New Specimens of a Titanosaur Sauropod from the Maastrichtian of Big Bend National Park, Texas
ABSTRACT New specimens of a titanosaur sauropod from Maastrichtian strata in Big Bend National Park, Texas, include well-preserved dorsal vertebrae in association with pelvic elements. AnteriorExpand
The youngest sauropod evidence in Europe
Titanosaur sauropods constituted one of the major dinosaur faunal components in Europe along the latest Cretaceous. Although they were abundant in the late Campanian–early Maastrichtian, titanosaursExpand

Abstract The horned dinosaurs (Ceratopsidae) were a diverse family of herbivorous dinosaurs originating in the Late Cretaceous in western North America (Laramidia). As one of the most species-richExpand
The diversity of sauropod dinosaurs and their first taxonomic succession from the latest Cretaceous of southwestern Europe: Clues to demise and extinction
article i nfo Southwestern Europe is a key setting to evaluate the diversity of non-avian dinosaurs before the end of the Cretaceous (below the K-Pg boundary). The ancient Ibero-Armorican Island,Expand
The oldest centrosaurine: a new ceratopsid dinosaur (Dinosauria: Ceratopsidae) from the Allison Member of the Menefee Formation (Upper Cretaceous, early Campanian), northwestern New Mexico, USA
An associated incomplete skeleton of a ceratopsid dinosaur from the Campanian deposits of the Allison Member of the Menefee Formation in New Mexico, USA is described. Although it was originallyExpand
The fragile legacy of Amphicoelias fragillimus (Dinosauria: Sauropoda; Morrison Formation - Latest Jurassic)
It is concluded that the reported size of A. fragillimus is most likely an extreme over-estimation, based on the ontogenetic change of Diplodocoidea vertebrae, the science of gigantism, and Cope’s own mannerisms. Expand
Appendicular Osteology of Dreadnoughtus schrani, a Giant Titanosaurian (Sauropoda, Titanosauria) from the Upper Cretaceous of Patagonia, Argentina
ABSTRACT The postcranial anatomy of giant titanosaurians remains poorly known because of a combination of preservational and collection biases. Dreadnoughtus schrani, a recently described, largeExpand
