Shaochilong was a carcharodontosaurid from the Ulanshuai Formation in China, dating back to the Turonian stage of the Late Creatceous, about 92 million years ago. Originally it was described as a species of Chilantaisaurus, but was reassigned as a primitive coelurosaur later. Then it was given its own genus in the carcharodontosaurids. It is a relatively advanced one, related closely to Tyrannotitan, Carcharodontosaurus, Mapusaurus, and Giganotosaurus. It is one of the youngest known allosauroids from the Laurasia, suggesting that they were still the dominant group on the continent at this time, rather than the tyrannosaurids. The rise of the tyrannosaurids was really at the end of the Cretaceous. It, like many members of its family, had teeth much like sharks.
