interval_notes:	Base-Santonian is lowest occurrence of the widespread inoceramid bivalve Cladoceramus undulatoplicatus. Following chart in Cobban et al. (2006), this level is equated to the base of the C. saxitonianus ammonite Zone of Western Interior; but Gale (chart to J.Ogg, Aug 2011) based on (Walaszczyk and Cobban, 2007) projects as uppermost S. depressus Zone; therefore base of Zone was put as 86.2 in GTS2012 based on 86.26 ?0.45 Ma by Siewert et al., 2011. Revised ages (Sageman et al., 2014) for base-C. saxitonianus ash-bed is 85.84 ?0.24; although their summary diagram with cycle-strat implies it is only about 1/4th to 1/3rd of a 405-kyr cycle above base-Santonian (inoceramid, which they had as ca. 86.3) => that offset (ca. 0.1myr) also used here. Cycle-strat duration from base-Santonian to next zone = 0.70 myr (Siewert et al., 2011); but revised in Sageman et al. (2014) as about 0.3 with assumption that the thickness is expanded by influx of terrigenous.
