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 ...
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 ...

Rebuilding a complete skeleton by comparing the size and morphology of bones to those of similar, better-known species is an inexact art, and reconstructing the muscles and other organs of the living animal is, at best, a process of educated guesswork. [143] Comparative size of Argentinosaurus to the average human
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).
A millimeter-sized sea animal could hold clues to the evolution of the human nervous system. While placozoans are simple animals only as big as a grain of sand, the blobs have unique cells that ...
Size of the type specimen compared with a human. Estimates based on measurements of the known parts of the skeleton suggest that the only known individual of Dreadnoughtus schrani was approximately 26 metres (85 ft) long and stood about 2 stories tall. [4] At 1.74 m, its scapula is longer than any other known titanosaur shoulder blade. [4]
