The two sheets show the diversity of dinosaurs in China, spanning some 200 million years, from the early Jurassic to the late Cretaceous periods.

Along with the stamps, China Post is also working with Zhao to develop dinosaur-themed merchandise.

Meanwhile, Zhao is working with writer Yang Yang on four children's picture books on dinosaurs.

The two founded a scientific art research institution, the Pecking Natural Science Organization in 2009. And they are working with scientists on images of dinosaurs to develop themed books, toys and other products.

The picture books will feature the Chinese dinosaur stamps and paintings showing Zhao's extensive knowledge.

Yang says the books are built up on the efforts of generations of Chinese scientists, and they want to share with readers that the dinosaur fossils found in China and the research by Chinese scientists are both world class.
