China Post has recently released on its WeChat account a free set of 16 animated stickers, or biaoqing bao, each portraying a type of dinosaur found in China.

In each sticker, the cartoon dinosaur expresses various emotions, such as shock, joy and anger, or depicts a scene, such as saying goodbye.

Featured genera include the Huayangosaurus from the Middle Jurassic, the remains of which were first found in Sichuan province in 1979, and Liaoningosaurus from the early Cretaceous period; two fossil specimens were collected in Liaoning province.

The stickers are to generate interest in a set of seven stamps, titled Dinosaurs of China, which China Post will issue on May 19.
