Prof. JIN Yugan, a celebrated paleontologist and a CAS member, died on June 26 at the age of 69. Top State leaders including Chinese President HU Jintao, Premier WEN Jiabao and CAS President LU Yongxiang sent their condolences.
Prof. Jin was born on December 26, 1937 in Dongyang, Zhejiang Province. Ever since his graduation from the Department of Geology of Nanjing University in 1959, he had been devoted his life to the studies on palaeontology and stratigraphy at the Nanjing Institute of Geology and Paleontology, CAS.
Prof. Jin was elected a CAS Member in 2001. He served as vice-president of the International Palaeontological Association, member of the International Commission of Stratigraphy, chairman of the Subcommission on Permian Stratigraphy and the Working Group on the Lopingian.
Prof. Jin had long been engaged in the studies of brachiopod fossils and scored rich achievements. For instance, the book series Brachiopod Fossils in China co-authored by him received a second prize from the National Award for Natural Science.
Prof. Jin was also a pacesetter in the studies of Carboniferous and Permian stratigraphy. In 1997, for instance, Prof. Jin and his co-workers published their work on Permian chronostratigraphic subdivisions, solving a long-standing problem in stratigraphic studies. He proposed a new international Permian stratigraphic framework for replacing the traditional Russian one used for 150 years. The new system was adopted by International Commission of Stratigraphy in 1998. After more than 20 years of hard work, the two international working groups headed by Prof. Jin were successful in setting up the GSSPs for the base of Wuchiapingian Stage and the Changhsingian Stage in China.
The mass extinction is a key issue in the exploration of changes of life and environment on earth. Prof. Jin for the first time in the world put forward the two-phase pattern of the end-Permian mass extinction and the pre-Lopingian Crisis in 1993. His paper Pattern of Marine Mass Extinction Near the Permian-Triassic Boundary in South China in
Science in 2000 attached great attention from the scientific community. Prof. Jin also hosted many key research projects supported by the National Natural Science Foundation of China, CAS and National Basic Research Program. In 1989, he established China's first open lab on palaeobiology and stratigraphy.
