摘要
Objective The Mesozoic strata in eastern Liaoning and southern Jilin are relatively well developed. Liu et al.(1963) studied Lycoptera in North China, and they mentioned the fossils of south Jilin, but they were not included in the study due to the lack of specimens and poor preservation. Ma and Sun(1988) studied fish fossils from the Sankeyushu section in Tonghua, Jilin, and laid the foundation for the study of fish fossils in this area.
