About Titanosaurus:

Titanosaurus is the signature member of the family of dinosaurs known as titanosaurs, which were the last sauropods to roam the earth before the K/T Extinction 65 million years ago. What's odd is, although paleontologists are sure that titanosaurs existed--their remains have been dug up all over the globe--they're not so sure about the status of Titanosaurus: this herbivore is known from very limited fossil remains, and to date, no one has found its skull. This seems to be a trend in the dinosaur world; for example, hadrosaurs (duck-billed dinosaurs) are named after the extremely obscure Hadrosaurus, and the aquatic reptiles known as pliosaurs are named after the equally murky Pliosaurus.
