“…From these rather exhaustive environmental records, many clades and geochemical proxies were studied to decipher the regional biotic recovery signal. The diversity of both benthic and nektonic organisms was analyzed mainly from foraminifers (Song et al, 2011, 2015b), brachiopods (Chen et al, 2015; Wang et al, 2017), bivalves (Yin, 1985; Huang et al, 2014), gastropods (Pan et al, 2003; Kaim et al, 2010), conodonts (Zhang et al, 2007; Zhao et al, 2007; Jiang et al, 2014; Brosse et al, 2015, 2016; Liang et al, 2016; Bai et al, 2017), and ammonoids (Chao, 1959; Xu, 1988; Mu et al, 2007; Brayard and Bucher, 2008; Brühwiler et al, 2008). Paleoenvironmental and paleoclimatic signals were also intensively studied from numerous South Chinese sections (Payne et al, 2004; Galfetti et al, 2007, 2008; Song et al, 2012, 2017).…”
