Diagram showing the size of Supersaurus (orange) compared with selected giant sauropods Supersaurus is among the largest dinosaurs known from good remains and quite possibly the longest discovered thus far, with the WDC specimen reaching 33–36 meters (108–118 ft) in length, the BYU specimen reaching perhaps 39 meters (128 ft) and a third ...
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like Supersaurus, Diplodocus, Apatosaurus, and Amphicoelias. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids ) are the only known sauropods to have re-evolved a short ...
Sauropoda is a clade of dinosaurs that consists of roughly 300 species of large, long-necked herbivores and includes the largest terrestrial animals ever to exist. The first sauropod species were named in 1842 by Richard Owen, though at the time, he regarded them as unusual crocodilians.
More recent and reliable estimates in 2023 have rescaled Bruhathkayosaurus to weigh around 110–130 t (120–140 short tons) with its most liberal estimate being 240 t (260 short tons), making it incredibly massive for such an animal. [17] If the upper unlikely size estimates were to be taken at face value, Bruhathkayosaurus would not only be ...
Size comparison of selected giant sauropod dinosaurs (from left to right): Supersaurus, Argentinosaurus, Diplodocus, Mamenchisaurus, and Sauroposeidon. A mega-sauropod, Maraapunisaurus fragillimus (previously known as Amphicoelias fragillimus), is a contender for the largest-known dinosaur in history.
The report said that it was the biggest known yet. In 2020 Molina-Perez and Larramendi estimated the size of the animal at 31 meters (102 ft) and 72 tonnes (79.4 short tons) based on the 1.75 meter (5.7 ft) long footprint. [23]
While dinosaurs such as Supersaurus were probably longer, fossil remains of these animals are only fragmentary and D. hallorum still remains among the longest known dinosaurs.
