..., unlike in eastern Yunnan, P1 starts from the middle part of the Yanjiahe Formation, while A. yanjiaheensis is reported from phosphatic clasts right below the Yanjiahe–Shuijingtuo boundary ( Fig. 6 ). This is probably due to the lack of phosphatized rocks that can preserve SSFs in the middle to upper...

.... Their lithostratigraphic units are correlative with those of the Songlin section ( Zhou et al. 2011 ). We recognized at least one K-bentonite near the base of the Niutitang Formation at the two sections. The Taishanmiao section is ca. 25 km north of Yichang City in Hubei Province. In the base of the Shuijingtuo Formation...
