interval_notes:	DASHED --Placed at base 0f C. furcillata Tethyan Ammon Zone by Mutterlose (GTS2020 chart, 29Dec2019; used here). Defines base of NC4, but difficult to pinpoint LAD, so LAD of "common" is used in some zonations (e.g., Charbonnier et al., 2013, Martinez et al., 2015) -- and is in uppermost O. nicklesi ammonite subzone in south France (19% up in Cycle V11; Martinez et al., 2015, supplement; used here). Final LAD has an approximation in mid-Hauterivian (arbitrarily put at 40% of S. sayni Zone here to avoid overlap with NC5). SEPM’98 had assigned as Middle of H. trinodosum s.z. (of N. pachydicranus Zone). With revised zonal scheme, this essentially is base of C. furcillata subzone.
