Titanosaurinae included Titanosaurus and the new genus Aeolosaurus, united by multiple features of the caudal vertebrae; the new clade Saltasaurinae was created to include Saltasaurus and the new genus Neuquensaurus, united by very distinct dorsals, caudals, and ilia; the new clade Antarctosaurinae was created to include Antarctosaurus ...
At the time, mass estimates ranged up to 180 tons, [14] which placed it in the same category as the blue whale and the equally problematic Bruhathkayosaurus. The naming of the chimeric Ultrasauros has a similarly complicated history. Ultrasaurus (with the final "u") was the original choice, and was widely used by the media after the discovery ...
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).
Size comparison of selected giant sauropod dinosaurs. The sauropods' most defining characteristic was their size. Even the dwarf sauropods (perhaps 5 to 6 metres, or 20 feet long) were counted among the largest animals in their ecosystem. Their only real competitors in terms of size are the rorquals, such as the blue whale.
The blue whale is the largest animal on Earth and likely the largest animal ever to have lived. While this ocean mammoth is dubbed “blue,” its color is more a reflection of the water it swims ...
"Titanosaurus" colberti - This species was the most well-known species of Titanosaurus, but has been moved into its own genus, Isisaurus. [15] [16] "Titanosaurus" australis - Known from relatively complete remains, but has been renamed Neuquensaurus. [15] "Titanosaurus" nanus - A small species found to be non diagnostic, and hence a nomen ...
Mature blue whales can reach 30 m (98 ft) in length, and the record-holder blue whale was recorded at 173 tonnes (190 short tons), [23] with estimates of up to 199 tonnes (220 short tons). [ 24 ] Another poorly known sauropod that shares similar size estimates to Bruhathkayosaurus is Maraapunisaurus fragillimus , which is based on a now-missing ...
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.
