Summary:

- This article reports the discovery of a new species of dinosaur called Qianzhousaurus sinensis, a type of tyrannosaur that lived in what is now China during the Late Cretaceous period, around 66-72 million years ago.

- Qianzhousaurus sinensis had an unusually long snout compared to other tyrannosaurs, which suggests it may have had a different feeding behavior or ecology compared to its more well-known relatives like Tyrannosaurus rex.

- The discovery of this new dinosaur species expands our understanding of the diversity and evolution of tyrannosaurs, a group of large predatory dinosaurs that were dominant in the later stages of the Mesozoic era.
