Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. D. schrani is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian; approximately 76–70 Ma) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina. It is one of the largest ...
Argentinosaurus (meaning "lizard from Argentina") is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina.Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t (72–88 short tons).
The heaviest blue whale on record weighed 190 metric tons (190 long tons; 210 short tons), [12] and the heaviest dinosaur known from reasonably good remains, Argentinosaurus, weighed 80 to 100 metric tons (79 to 98 long tons; 88 to 110 short tons), although if the size estimates can be validated, it could still be lighter than Bruhathkayosaurus ...
Scientists have unearthed in Argentina's Patagonian wilderness fossils of what may be the oldest-known member of the dinosaur group known as titanosaurs that includes the largest land animals in ...
The femur of specimen EMF164 has a length of 2.146 metres (7.04 ft), similar in size to the femora of Futalognkosaurus and Dreadnoughtus, though smaller than those of Patagotitan. The describing authors deliberately abstained from providing a size estimate, as it is notoriously difficult to obtain reliable results for sauropods.
Sauropoda (/ s ɔː ˈ r ɒ p ə d ə /), whose members are known as sauropods (/ ˈ s ɔːr ə p ɒ d z /; [1] [2] from sauro-+ -pod, 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs.
Macronaria is a clade of sauropod dinosaurs.Macronarians are named after the large diameter of the nasal opening of their skull, known as the external naris, which exceeded the size of the orbit, the skull opening where the eye is located (hence macro- meaning large, and –naria meaning nose).
Puertasaurus is a genus of sauropod dinosaur that lived in South America during the Late Cretaceous Period.It is known from a single specimen recovered from sedimentary rocks of the Cerro Fortaleza Formation in southwestern Patagonia, Argentina, which probably is Campanian or Maastrichtian in age.
