Recently, our company was lucky enough to collect two extinct marine reptiles, Zhou Long, found in Guizhou Province, China. At present, only fossils are left in the world. 1957, Mr. Hu Chengzhi, geological museum, China, and Mr. Cao Zetian, Guizhou Provincial Museum collected a batch of small reptile fossils in Xingyi Village, Guizhou Province, which were identified as a new genus and species of LEPIDOPTERA by Professor Yang, Institute of vertebrate paleontology and Paleoanthropology, Chinese Academy of Sciences, and specially named' Keichouarus Hui' (Keichouarus Hui Young1958) in memory of Hu who collected the fossils for the first time. The discovery of "Hui Zhoulong" represents the first discovery of primitive pterosaurs in Asia.
Generally speaking, there are only one or two dinosaur footprints in a dinosaur footprint point, but the dinosaur footprints in Lizhuang footprint point include three-toed medium-sized theropod dinosaurs, small theropod dinosaurs, micro theropod dinosaurs and two-toed small deinonychus footprints left by carnivorous dinosaurs.
Hui Zhou Long lived in the Late Triassic more than 230 million years ago, and was distributed in Ding Xiao, Xingyi County, Guizhou Province, China. Its main characteristics are as follows: a medium-sized marine animal, whose limbs have not degenerated into flippers, may be engaged in amphibious life and mostly live in coastal areas; The temporal foramen on the skull is small and the orbit is large and round; The skull is triangular, the maximum width is at the orbit, the snout is small and sharp, the teeth are of the same type, sharp and round, and the dentition is not closely arranged.
Recently, our company was lucky enough to collect two Zhou Longhui fossils. The Zhou Longhui of this fossil specimen is 20-30 cm long. According to the calculation of paleontologists, the probability that ancient creatures can form fossils after death is about one in a million, and the probability that fossils are discovered is about one in a million. It is really difficult to collect valuable fossil specimens, and the rarity of fossils can be seen. It is no exaggeration to use "extremely rare" to describe the fossils in Zhou Longhui. Call it "Jane" because it is the smallest dragon; It is called "rare" because only Xingyi, Guizhou has output in the world today. Because of its high scientific research value and ornamental value, Zhou Long fossils have become the collections of paleontologists, enthusiasts, ornamental stone lovers and collectors.
With the long evolution and instantaneous turmoil, the original dominant dinosaurs on the earth have disappeared from the earth, but the evidence of their existence still exists in the form of fossils.
Zhang Jianping, a professor of stratigraphic paleontology at China Geo University, said that the fossils related to dinosaurs mainly include dinosaur bones, dinosaur footprints, dinosaur eggs and dinosaur feces. "dinosaur footprints can only be preserved on the ground where the temperature, viscosity and particle size of sediments are suitable."
These footprints can help scientists understand the habits of dinosaurs. Zhang Jianping believes that dinosaur footprints can provide information about dinosaur species, size, quantity and relative abundance, walking direction and speed. In addition, dinosaur footprints can also provide information such as the shape of dinosaur feet and the number of toes. In some cases, dinosaur footprints also contain skin prints, which provides valuable information for studying dinosaur skin structure and dinosaur recovery.
