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 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 and ...
In other studies, Argentinosaurus has been estimated at 65–96.4 tonnes (71.7–106.3 short tons). [11] [16] [17] [18] In 2019, Paul noted that the articulated length of the back vertebrae was larger in Argentinosaurus (4.47 metres (14.7 ft)) than in Patagotitan (3.67 metres (12.0 ft)), making it impossible for Patagotitan to
Size comparison between a human and two species of Basilosaurus, B. cetiodes (dark blue) and B. isis The heaviest archeocete , and possibly the heaviest known mammal was Perucetus , with weight estimated at 85–340 t (84–335 long tons; 94–375 short tons), while length is estimated at 17.0–20.1 meters (55.8–65.9 ft), [ 108 ] possibly ...
Size of a few specimens compared to a human. Mapusaurus was a large theropod, but slightly smaller in size than its close relative Giganotosaurus, with the largest specimen measuring around 10.2–12.2 metres (33–40 ft) long and weighing up to 3–6 metric tons (3.3–6.6 short tons). [2] [7] [8] [9]
In 2020, Molina-Perez and Larramendi suggested that the 2 m (6.6 ft) long tibia is probably a fibula, and estimated the size of the animal at 37 m (121 ft) and 95 metric tons (105 short tons). [21] By comparison, the titanosaur Argentinosaurus is estimated to have reached 35 m (115 ft) in length, and to have weighed 65–100 tonnes.
These evolved into saurischia, which saw a rapid increase of bauplan size, although more primitive members like Eoraptor, Panphagia, Pantydraco, Saturnalia and Guaibasaurus still retained a moderate size, possibly under 10 kg (22 lb). Even with these small, primitive forms, there is a notable size increase among sauropodomorphs, although scanty ...
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 ...
