Excavation of the dorsal and caudal vertebrae and pelvis of Qunkasaura. The holotype specimen of Qunkasaura is a partial skeleton belonging to a single individual. It is part of a bonebed discovered in 2007, which includes the associated skeletons of multiple titanosaur taxa, as well as other dinosaurs, eusuchians, and many other animals.
Titanosauria have the largest range of body size of any sauropod clade, and includes both the largest known sauropods and some of the smallest. [25] One of the largest titanosaurs, Patagotitan, had a body mass estimated to be 69 tonnes (76 tons), whereas one of the smallest, Magyarosaurus, had a body mass of approximately 900 kilograms (2,000 lb).
One of the titanosaur tail vertebrae bore marks that could have been made by Tyrannotitan chubutensis, either through scavenging or hunting. A total of 223 bones of seven different individuals of the new species were found on three levels at the site, indicating three different occasions on which the animals were deposited at the site.
Patagotitan mayorum, another titanosaur found in the same region, had an estimated length of about 130 feet, researchers said in a CONICET news release, and may have weighed as much as 70 tons, a ...

Saltasaurus was one such titanosaur sauropod, and lived around 70 million years ago. When it was first discovered, in 1975, it forced palaeontologists to reconsider some assumptions about sauropods as Saltasaurus possessed crocodile-like armour (osteoderms) 10 to 12 centimetres (4 to 5 in) in diameter.
Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. D. schrani is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian; approximately 76–70 Ma) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina.
