interval_notes:	2 events are used, depending on morphotype. Small is earlier. Large (USED HERE) is base of M. fallax ammonite zone at Col de Palluel (Gale et al., 2011) (used here, because have cycle-strat for that foram zone). Bown’98 has schematically shown as 90% up in M. inflatum Zone, which is same numerical-age level. Bralower-Leckie, 1997, had put slightly lower -- coeval with FAD of foraminifer R. ticinensis. SEPM’98 assigned Boreal FAD as 7/10 up in E. loricatus Z., E. meandrinus s.z. or Tropical as just below (0.15 myr) the base of H. orbignyi subzone.

base notes	Bown shows as 30% up in S. dispar Ammonite Zone (now interval from base M.rostratum to top A. briacensis Zones), but found higher [Sudeep Kanungo, UCL thesis, June 2005; and pers. commun., Oct 2005 at EGI], therefore assigned here as 60% up. Could be higher (40% up in R. appenninica Foram Zone was in TSC-tropical of 2010). SEPM’98 assigned as Middle of M. perinflatum subzone. [ammonite zones have been reorganised in this interval and are confusing. Equation in workbook gave 0.6 (P. rostratum + P. perinflatum + TAZ]				comp notes
