Tsintaosaurus spinorhinus
"spine-nosed Qingdao lizard"

     Tsintaosaurus is one of the more interesting looking hadrosaurs (so called "duck billed" dinosaurs). Like other lambeosaurines, Tsintaosaurus had a species-specific crest or horn adorning its head. In this case, there had been controversy over whether or not Tsintaosaurus' unicorn-like horn was actually just a misplaced nasal bone. The discovery of another specimen with the bone in the same position seems to confirm that it was in fact a horn, probably used for display.

     At 10m (33ft.) Tsintaosaurus was an average-sized hadrosaur, found in the Late Cretaceous of China. The decorative frill of skin running from the crest down the back is speculative, but is supported by similar structures found in mummified hadrosaurine specimens.
