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).
Macroelongatoolithus (41HV003-16) nest with eggs. While they were once considered to be the eggs of large tyrannosaurids (like Tarbosaurus) on the basis of their huge size, [9] egg shape and microstructural evidence suggests they are eggs of gigantic oviraptorosaurs (like Beibeilong or Gigantoraptor).

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 ...
Titanosauria have the largest range of body size of any sauropod clade, and includes both the largest known sauropods and some of the smallest. [25] One of the largest titanosaurs, Patagotitan, had a body mass estimated to be 69 tonnes (76 tons), whereas one of the smallest, Magyarosaurus, had a body mass of approximately 900 kilograms (2,000 lb).
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 ...
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).

[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).
