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).
Dinosaur eggs vary greatly in size and shape, but even the largest dinosaur eggs (Megaloolithus) are smaller than the largest known bird eggs, which were laid by the extinct elephant bird. Dinosaur eggs range in shape from spherical to highly elongated (some specimens three times longer than they are wide).
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 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 ...
Scientists think that once the Argentinosaurus hatched from its egg, it would continue growing for the entirety of its life. #25. ... Dinos may have been big in size, but not very intelligent. The ...
This is the largest known dinosaur nesting site in the world, where many nests of eggs are preserved over a stretch of several kilometres. Attenborough struggles to walk without stepping on dinosaur eggs, and discusses the site with one of its discoverers, Dr Luis Chiappe. Dinosaur eggs occur in four separate layers, indicating the dinosaurs ...

[13] [14] Wedel also criticised the polygon-based method that Carballido and colleagues used to compare the sizes of Patagotitan and Argentinosaurus ' vertebrae, noting that the former was largely empty space. [15] In other studies, Argentinosaurus has been estimated at 65–96.4 tonnes (71.7–106.3 short tons).
