“…Various angiosperm families have been identified based on leaves and fruits found from a layer of light brown diatomite and an underlying layer of blue‐grey mudstone, such as Fagaceae (Wang, 2018), Leguminosae (Lin, Wong, Shi, Shen, & Li, 2015), Dipterocarpaceae (Shi, Jacques, & Li, 2014), Euphorbiaceae (Jacques, Shi, Su, & Zhou, 2015; Wang et al, 2017a), Clusiaceae (Wang et al, 2019, 2018), Lauraceae (Wang et al, 2017b), Rhamnaceae (Dong, Sun, Mao, Jin, & Wang, 2018), and Altingiaceae (Dong et al, 2018). The majority of the extant members of these families grow today in pantropical regions, some of them extend to the temperate zone (Dong, Sun, Mao, Yan, et al, 2018).…”
