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 specimen potentially exceeding 40 meters (130 ft) in size.
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.
Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists. Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds , which can weigh as little as two grams, to the extinct titanosaurs , such as Argentinosaurus ...
Argentinosaurus 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 ...

Dinheirosaurus is a genus of diplodocid sauropod dinosaur that is known from fossils uncovered in modern-day Portugal. It may represent a species of Supersaurus. [1] The only species is Dinheirosaurus lourinhanensis, first described by José Bonaparte and Octávio Mateus in 1999 for vertebrae and some other material from the Lourinhã Formation.
Ultrasaurus (meaning " ultra lizard" [2]) is a genus of sauropod dinosaur discovered by Haang Mook Kim in South Korea.
