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).
Partial leg and foot bones with fragments of vertebrae [305] May be a nomen dubium [305] or belong to the genus Plateosaurus, [302] several hip bones were described with the rest of the holotype which have been lost [305] Gryponyx africanus: SAM 3357-3359 [36] Iziko South African Museum: Sinemurian: Upper Elliot Formation, South Africa
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.
Sauropod necks have been found at over 15 metres (49 ft) in length, a full six times longer than the world record giraffe neck. [45] Enabling this were a number of essential physiological features. The dinosaurs' overall large body size and quadrupedal stance provided a stable base to support the neck, and the head was evolved to be very small ...
The most important metric for understanding the anatomy of a fossil animal is the types of bones. The completeness statistics for Dreadnoughtus schrani are as follows: 116 bones out of ~256 in the entire skeleton (including the skull) = 45.3% complete; 115 bones out of ~196 in the skeleton (excluding the skull) = 58.7% complete
The massive specimen, named Apex, will be on display at the American Museum of Natural History for four years, the museum said.

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.
