base notes	Ca. 80% up in C5AAr in Scherer et al. (2007) chart, which has "Denticulopsis simonsenii (FCO)" as base; but their range chart and Barron (SEPM, 1998) use First-Common (FCO) Denticulopsis hustedtii as the basal marker -- My guess is that the "s. ampl." is for "simonsenii"? Dual markers (FCO and LCO) for Zone NPD5A = Crucidenticula nicobarica Interval Zone (defined by Akiba, 1982), Denticulopsis hustedtii s. ampl. (FCO) was earlier used for this species -- Barron (19May2020) advised to use simonsenii.				comp notes	ON TSC this event is labelled as FAD Denticulopsis simonsenii, and there is another FAD Denticulopsis simonsenii about 1Ma lower, working from the notes I have relabelled this one as FCO Denticulopsis simonsenii [JRY]
