Stratigraphy
| Geological group: | Chongqing | Formation: | Shaximiao | Member: | Upper |
| Stratigraphic resolution: | bed | ||||
| 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). | |||||

| Collectors: | G. Kuan & A. Zhou | Collection dates: | 1957, 1978 |
| Collection method comments: collected by Kuan (Guan) in 1957, then Zhou at same site in 1978. collected in 1957 by Yaowu Guan of the Sichuan Regional Petroleum Exploration Office from Taipingzhai. In November of 1978, Angui Wang from the QuxianCounty Hydroelectric Office noted numerous occurrences of fossil bone at the locality thatproduced Chialingosaurus. Re-excavation was thereby undertaken by a consortium including Shiwu Zhou from the Chunking Natural History Museum, Xingyao Li from the Quxian County Cultural Office, and Shengquan Xu of the Hydroelectric Office | |||
