Titanosaurus (meaning 'titanic lizard' - named after the mythological 'Titans', deities of Ancient Greece) is a dubious genus of sauropod dinosaurs, first described by Lydekker in 1877.[1] It is known from the Maastrichtian (Upper Cretaceous) Lameta Formation of India.
Titanosaurus are estimated to have grown up to 9–12 metres (30–40 ft) long and about 13 tons in weight. Titanosaurus has traditionally been treated as a "wastebin taxon" for poorly preserved sauropod remains that demonstrate a distinctive vertebrae anatomy. The original Titanosaurus remains consist only of limb bones and a few vertebrae that have these characteristics. However, discoveries of more and better-preserved titanosaur species have shown that these once distinctive features are in fact widespread across many genera. Therefore, Titanosaurus itself is considered a nomen dubium ("dubious name") by most paleontologists, since the original Titanosaurus specimens cannot be distinguished from those of related animals.[2]
