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).
Bones from several similar-sized individuals were incorporated into the skeleton now mounted and on display at the Museum für Naturkunde Berlin; [22] this mount is 12–13.27 metres (39.4–43.5 ft) tall and 21.8–22.5 metres (72–74 ft) long, [23] [24] [25] and would have belonged to an animal that weighed between 30,000 to 60,000 kilograms ...
A study by Martin Sander and colleagues in 2006 examined eleven individuals of Europasaurus holgeri using bone histology and demonstrated that the small island species evolved through a decrease in the growth rate of long bones as compared to rates of growth in ancestral species on the mainland.

Sauroposeidon (/ ˌ s ɔːr oʊ p oʊ ˈ s aɪ d ən / SOR-o-po-SY-dən; meaning "lizard earthquake god", after the Greek god Poseidon [3] [4]) is a genus of sauropod dinosaur known from several incomplete specimens including a bone bed and fossilized trackways that have been found in the U.S. states of Oklahoma, Wyoming, and Texas.
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).
They conceded that comparison with Tyrannosaurus was difficult due to the disarticulated state of the cranial bones of Giganotosaurus, but noted that at 1.43 m (4.7 ft), the femur of Giganotosaurus was 5 cm (2 in) longer than that of "Sue", the largest known Tyrannosaurus specimen, and that the bones of Giganotosaurus appeared to be more robust ...
Macronaria is a clade of sauropod dinosaurs.Macronarians are named after the large diameter of the nasal opening of their skull, known as the external naris, which exceeded the size of the orbit, the skull opening where the eye is located (hence macro- meaning large, and –naria meaning nose).
Bruhathkayosaurus (/ b r uː ˌ h æ θ k eɪ oʊ ˈ s ɔːr ə s /; meaning "huge-bodied lizard") is a controversial genus of sauropod dinosaur found in the Kallamedu Formation of India.The fragmentary remains were originally described as a theropod, but it was later determined to be a titanosaurian sauropod.
