Zhao Chuang (32), a Beijing-based artist, who designed the stamps, has drawn several birdlike dinosaurs for Chinese paleontologists who have found the fossils, and his images appear at scientific articles in international magazines and journals, says: "Dinosaurs are still with us today" and explains this by saying that dinosaurs are accepted as the ancestors of birds, and that birds make up the largest proportion of vertebrates in the world. The illustrator believes that to propagate the knowledge of dinosaurs, more ways should be used, including postage stamps, which he calls "a museum on paper".
For security reasons and to attract philatelists, the stamps printed with special ink and used fluorescent technology that allows to see the dinosaurs bones and normally invisible security number of every stamp under UV light.

Dinosaurs were a type of reptile that came into existence during the Mid to Late Triassic (approximately 234 million years ago). Among them, the non-avian dinosaurs perished from the world’s stage at the end of the Cretaceous Period (approximately 66 million years ago), and the species that were fortunate enough to avoid extinction subsequently evolved into modern-day species of birds. China is rich in dinosaur fossils, and is often referred to as the nation with the richest dinosaur remains. Even though formal research of dinosaurs in China began at a relatively late stage, this field of study has developed rapidly. After nearly a century, Chinese research is now at the forefront of the paleontological world. By the end of May 2014, China had officially named 244 different species of dinosaurs, ranking first overall in the world.
featured on the souvenir sheet, existed during the Late Jurassic.
Fossils of this specimen have been discovered in Sichuan, Chongqing,
Xinjiang and other regions of China. It had a huge body that was
approximately 22 meters in length, of which its slender neck accounted
for almost half of its total body length. The neck of the
Mamenchisaurus was set at an angle from the ground, in order to raise
its head higher. Moreover, it had a very broad chest and rounded
abdomen, in addition to an enormous “tail hammer” that was positioned
at the end of its tail.
Note: Yang Zhongjian (1 June 1897 – 15 January 1979), courtesy name Keqiang, also known as C.C. (Chung Chien) Young, was one of China's foremost vertebrate paleontologists. He has been called the 'Father of Chinese Vertebrate Paleontology'.

Its fossil was discovered in Laiyang, Shandong Province.
had a very strong and powerful body, which was approximately 8 meter
long, as well as a large and ﬂat snout, and a tube-like nasal bone,
which was positioned vertically on its head. This creature moved with
four limbs and preferred to live withothers together in a herd.
In 1950, at Hsikou, near Chingkangkou, in Laiyang, Shandong, in the eastern part of China, various remains of large hadrosaurids were uncovered. In 1958 these were described by Chinese paleontologist Yang Zhongjian ("C.C. Young") described it as the type species Tsintaosaurus spinorhinus. The generic name is derived from the city of Qingdao, earlier often transliterated as "Tsintao". The specific name means "with a nose spine", from Latin spina, and Greek ῥίς, rhis, "nose", in reference to the distinctive crest on the snout.
The earliest fossils of this specimen were discovered in
Chongqing n 1976. During a thunderstorm in June 1976,
Lyu Xiangzhi, deputy commander of a local reservoir, was on his way to
check a dam with his colleague when they stumbled upon a white object
exposed from a rock. It was very hard and looked similar to an animal
bone. Later, an expert identified the fossil to be a carnivorous
head with well-preserved jaw teeth. The local government conducted a
large excavation project around where the fossil head was found. About
20 days later, a complete fossilized dinosaur was found. This
Yangchuanosaurus fossil is now preserved at the Chongqing Natural
History Museum, as a major treasure of the museum.
| The Huayangosaurus
belongs to the Stegosauria, and lived during the
Middle Jurassic. In 1979 and 1980, remains from twelve
stegosaurian individual animals
were recovered from the Dashanpu Quarry near Zigong in Sichuan. They
were named and described by Dong Zhiming, Tang Zilu and Zhou Shiwu in
It was approximately 4.5 meters long, it was also much smaller than its famous cousin Stegosaurus, with powerful and well-built limbs, and 32 bone plates that were lined along its back in two symmetrical rows. In addition, its shoulders and tail were girded with long spikes. Like other stegosaurians, Huayangosaurus was a quadrupedal herbivore with a small skull and a spiked tail.
was a carnivorous creature. It lived in the
Early Cretaceous, and its fossils were discovered in Liaoning Province.
Its body was only 1~2 meters long. Described in 1996, it was the first
dinosaur taxon outside of Avialae (birds and their immediate relatives)
to be found with evidence of feathers. It was covered with a coat of
very simple filament-like feathers. Moreover, it is
also the ﬁrst dinosaur to successfully have its color determined by
Sinosauropteryx was a small theropod with an unusually long tail and short arms and had several features unique among all other theropods. It had 64 vertebrae in its tail. This high number made its tail the longest relative to body length of any theropod. Its hands were long compared to its arms, about 84% to 91% of the length of the rest of the arm (humerus and radius), and half the length of the foot. The first and second digits were about the same length, with a large claw on the first digit. The first fingers were large, being both longer and thicker than either of the bones of the forearm.
Relative to its size, Gigantoraptor had unusually slender limbs and lengthy legs.
The researchers theorize that Gigantoraptor may have used its feathers for display or for incubating its eggs. Past studies suggest oviraptorosaurs may have had long feathers on their arms and bodies for covering their eggs.
The diet of Gigantoraptor is uncertain. Although some oviraptorosaurs, are thought to have been mostly herbivorous, Gigantoraptor had long hind legs with proportions that allowed for fast movement, and large claws, a combination that is not usually found in herbivores of this size, therefore it is suggested that Gigantoraptor was also a herbivore and used its speed to escape predators.
Like Archaeopteryx, well-preserved fossils of Microraptor provide important evidence about the evolutionary relationship between birds and dinosaurs. Microraptor had long pennaceous feathers that formed aerodynamic surfaces on the arms and tail but also on the legs. This led paleontologist Xu Xing in 2003 to describe the first specimen to preserve this feature as a "four-winged dinosaur" and to speculate that it may have glided using all four limbs for lift. Subsequent studies have suggested that Microraptor was capable of powered flight as well. Microraptor was among the most abundant non-avialan dinosaurs in its ecosystem, and the genus is represented by more fossils than any other dromaeosaurid, with possibly over 300 fossil specimens represented across various museum collections.
