Tuojiangosaurus multispinus was a herbivorous stegosaurid dinosaur from the Late Jurassic period (around 150 million years ago). Its fossil was discovered near River Tuo, Sichuan Province, from which the species gained its name. Tuojiangosaurus was 7 to 8 metres long, with a triangular head, two rows of upward spiked plates running down over its neck, spine and tail, and two pairs of outward pointing spikes at the end of its tail. Mainly living in forests, the species fed predominantly on low vegetation. The fossil of Tuojiangosaurus is the first recorded discovery of a well-preserved stegosaurus skeleton in Asia.Also in the issue Chinese Dinosaurs:

Stamp Tuojiangosaurus multispinus 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.
