Titanosaurus was 9-12 meters (30-40 ft) long and weighed about 13 tons. 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.
