Recently, 77-year-old Wang Chengyuan submitted a monograph. He has been engaged in the study of paleontological tooth-shaped thorns for a lifetime, and he is also constantly making his own contributions to the integration of Chinese stratigraphic work with international standards.

He and his peers have established 237 tooth-shaped thorn fossil belts in China's Cambrian to Triassic marine strata; he has traveled to 37 countries and regions in europe, the United States, Asia and Australia, covering all provinces and autonomous regions in the country, and studied the tooth-shaped thorns in 25 provinces and autonomous regions in China; he is the leader of the Chinese tooth-shaped thorn discipline, and the Chinese tooth-shaped thorn discipline has entered the world and strived to move forward.

In 1963, Wang Chengyuan graduated from Peking University and was admitted to the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences as a graduate student.

When Wang Chengyuan was a graduate student, the paleontological phyla was lamellar, and after two years of professional study, he realized that the discipline of dental spines had great prospects for development and decided to open up the research of dental spines.

Wang Chengyuan resisted the pressure and published a number of articles, the earliest study of The Chinese Silurian, Devonian, Carboniferous, Triassic tooth-shaped spines, the formation of the Chinese tooth-shaped thorn discipline group; the earliest tooth-shaped thorn as the leading fossil phyla, to solve many stratigraphic problems that China has not solved for many years.

"By correcting the era of other fossil phyla, I have made major revisions to the era of the foam inner ditch coral belt, the era of BuhadinBe, the era of the Solanowe dragon belt, and the era of guizhou dragon determined by China's famous academic authorities and applied in China for more than half a century, and made correct domestic and foreign comparisons." Wang Chengyuan said.

Wang Chengyuan also first discovered the Permian Gondwana cold-water phase tooth-shaped thorn in Tibet; the section of the Four Red Mountains of Debao, Guangxi, which he studied, was recommended by the Devonian Branch of the International Stratigraphic Commission as a reference section for the upper and lower boundaries of the Upper and Lower Devonians in Asia; first quoted the concept of organ classification and made a comprehensive revision of the Silurian tooth-shaped thorn form genus established in China; in 2010, he published an English monograph in the United Kingdom, establishing a new genus and new family of tooth-shaped thorns.

"Today, tooth-shaped thorns are one of the fastest growing and most important paleontological disciplines at home and abroad, playing an important role in boundary strata, geological mapping, prospecting and tectonic research." Wang Chengyuan said.

There was a fierce debate over the layered line of the Lepingtong bottom boundary, and finally the International Stratigraphic Committee adopted the point of the Leping bottom boundary layer type first determined by Wang Chengyuan, that is, the location of the 6k section of Penglai Beach in Guangxi. The internationally accepted points of the golden nails of the top and bottom boundaries of the Leping system were determined by Wang Chengyuan based on the tooth-shaped thorns. Wang Chengyuan has published more than 350 articles, is one of the authors with the most academic papers in the Institute of Southern Antiquities, and is also the first scholar in China's paleontological community and Jiangsu Province to receive the Humboldt Scholarship in Germany. Since his retirement in 2004, he has published more than 80 academic papers. He has been invited to many countries to solve major stratigraphic problems. He has won the first prize of natural science of the Chinese Academy of Sciences, the third prize of the National Science and Technology Progress Award, the second prize of the Jiangsu Provincial Science and Technology Progress Award and many other awards. He enjoys special allowances from the national government.

From 2010 to 2015, Wang Chengyuan published 4 monographs in succession, and one monograph has been submitted. Today, as the leader of the dental spine discipline of the Chinese Society of Micro paleontology, Wang Chengyuan actively advocates the leading fossil phyla and promotes the application of international stratigraphic surfaces in China, which has been valued by many regional geologists.
