Stratigraphy comments: Several radiometric ages have been reported for the Shaximiao Formation, including 167 Ma or 172 Ma (Zong and Shi, 1997), 167–172 Ma or 178–169 Ma (Gou et al., 2000), 163±3 Ma (Li et al., 2010), 160±4 Ma (Luo et al., 2014), 158±7 Ma (Qian et al., 2016), and 159±2 Ma (Wang et al., 2018). However, more recent studies suggest an older age; Dai et al. 2022 reported a maximum depositional age for the bone-bearing layers of the lower member of the Shaximiao formation to be Bjaocan. Zhou et al. 2022 also supported a late Middle Jurassic age for the Shaximiao Formation (Bathonian-Callovian). |
