“…He has also obtained abundant fossil specimens from Carboniferous and Permian strata, and, together with other experts, compiled several regional palaeontological atlases (i.e., Jin & Liao, 1974; Jin, Liao, & Fang, 1974; Kong et al, 1996; Z. T. Liao, 1964; Z. T. Liao & Sun, 1974; G. P. Wang et al, 1982; Y. Wang, Jin, & Fang, 1966), which are greatly helpful for regional geological survey and research. Liao was also one of the key members of the working teams led by Professors Jingzhi Yang and Jinzhang Sheng, respectively, for nation‐wide correlations of the Carboniferous and Permian strata, and they completed several regional stratigraphical correlation charts of Carboniferous and Permian and studies on their boundaries (Fang et al, 1999; Hance et al, 1997; Z. T. Liao, 1993, 1999a, 2011, 2013; Z. T. Liao et al, 2010; J. Z. Sheng et al, 1982; Q. Y. Sheng, Wang, Qi, & Liao, 2021; C. Y. Wang et al, 1987; X. D. Wang et al, 2013, 2019;X. J.
