interval_notes:	DASHED (Brian Huber, email Jan2016) at 0.5myr below Base of Furcata (base C11): "The eximius datum is too low and is being revised by David Watkins based on our Tanzania work (paper in prep probably for Marine Micropaleo). It should be placed just below the FAD of furcatus." Was GTS2012 -- For now, FAD of E. eximius assigned as assigned as 80% up in M. nodosoides Zone (from schematic diagram in Burnett’98). Also put as coeval with foram H. helvetica LAD; but it seems diachronous relative to LAD of H. helvetica (above LAD at Demerara Rise Leg 207; within Helvetica zone at Tanzania and S. Atl. Pueblo (USA) => can get cyclestrat for both events (Dave Watkins; but he needs to check it). SEPM’98 assigned FAD at about 1 myr higher. Dual-markers (Eiffellithus eximius, Lucianorhabdus maleformis) for base of CC12; but separated in Burnett’98. SEPM’98 had assigned both FADs as middle of P. percarinatus Z.
