interval_notes:	The latest Ladinian rocks, the Yangliujing Formation, are 490 m of shoaling-upward carbonate cycles of grapestone and bioclastic grainstone, fenestral limestone, and stromatolitic dolomudstone, commonly overprinted by extensive subaerial diagenesis." (Enos et al., 1998, 2006). Base placed here as base of Longobardian. However, Enos et al (2006) also imply that these may span entire Ladinian. Uncertain
