Titanosaur (clade Titanosauria) is named after the early god Titan in Greek mythology. The fossil of titanosaur was discovered in the Lamita Formation in India in 1877, and the geological age is the Maastrichtian stage of the Upper Cretaceous. Other species of titanosaur have also been found in southern Europe and South America.
In 2014, a titanosaur fossil was discovered in the desert of Patagonia, Argentina. It is said that a total of 223 fossils were found at the excavation site, including a huge leg bone of about 2.44 meters. Its unique shape and size led paleontologists to believe that they had found a new species, the largest known dinosaur fossil.
On January 15, 2016, at the American Museum of Natural History in New York, the "Titanosaur" exhibition will officially open to visitors. 37.2 meters long "Titan Dragon" is the newly discovered behemoth that the museum has exhibited for the first time. This article will explain more facts about these giant dinosaurs.
Titanosaur General Descriptions
Titanosaurs are a diverse group of sauropod dinosaurs classified in the clade Titanosauria, which lived from the Late Jurassic Epoch (163.5 million to 145 million years ago) to the end of the Cretaceous Period (145 million to 66 million years ago). Titanosaur fossils have been found on all continents except Antarctica and include some 40 species. Titanosaur is the largest terrestrial animal known, some even approaching the size of modern whales. They were mainly active in the southern hemisphere, a ferocious and violent group of herbivorous dinosaurs.
Complete Titanosaurus fossils are rare, so many mysteries remain. Titanosaurus has traditionally been a "concentration of unclassified species," but many sauropod fossils with unique vertebral physiology have been classified as Titanosaurs. The first titanosaur fossils discovered consisted of limb bones and a few vertebrae, which had unique features. Like other sauropods, titanosaurs were herbivorous quadrupeds with long tails, long necks, small heads with large nostrils, raised nasal bones, and small, spike-like teeth. Skin traces from the fossils revealed smaller scales inlaid around large scales on their skin.
Titanosaur Specices' Size
A sauropod subgroup called the Titanosauria contained the largest sauropods. Titanosaur size varied greatly. The following sections describe titanosaurs of varying sizes.
According to some sources, one of the largest titanosaurs possibly was Dreadnoughtus. It had roughly 26 meters (about 85 feet) and an estimated mass of 59 metric tons (about 65 tons). Dreadnoughtus is known from rock deposits of southern Patagonia, Argentina, about 77 million years ago.
Paleontologists said that the southern titanosaur discovered in the Australian outback has been identified as a new species and is one of the largest dinosaurs on earth, which is the length of a standard basketball court. Southern Titan (scientific name: Australotitan Cooperensis) comes from the Titanosaur family and is one of the 15 largest dinosaurs in the world. Experts estimate that the southern titan could be 5 to 6.5 meters tall and 25 to 30 meters long.
Argentinosaurus has been known to science since 1993. Fossils were originally discovered in 1987. Although no complete skeletons of Argentinosaurus have been found, estimates of the dinosaur's length range from 37 to 40 meters (about 121 to 131 feet), and it was thought to have weighed 90 to 100 metric tons (99 to 110 tons).
Titanosaurs were the latest large group of sauropod dinosaurs to appear before the Cretaceous-Tertiary extinction event. They lived between 90 million and 65 million years ago and were the dominant herbivores. Titanosaurs are widely distributed, especially in the southern continents (Gondwana), and even sauropod fossils belonging to Titanosaurus have been found in Queensland, Australia.
