Yangchuanosaurus shangyouensis was an enormous carnivorous theropod dinosaur from the Late Jurassic period (around 150 million years ago). It was named after the excavation of the first fossil during the construction of a reservoir in Yangchuan, Chongqing. It was 8 to 10 metres long, with sharp teeth and nimble forelimbs ending with three large and razor-sharp claws. Adept at living in hillocks and woods, it mainly preyed on small animals. The fossil skeleton discovered in 1976 is the most intact fossil of a sizable theropod ever found in China.Also in the issue Chinese Dinosaurs:

Stamp Yangchuanosaurus shangyouensis it reflects the thematic directions:
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is a subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds.
