interval_notes:	Voight et al. (2011, submitted to EPSL) shows this datum (base UC18) at about 15% up in B. sumensis Belemite Zone (and projects to C31r.2 at Gubbio; and used here). Huber et al’ project age as 70.6 Ma relative to GTS04 magnetics = C31r.16 (nearly same as Voight). Burnett’98 schematicaly shows this LAD at about 1/3rd up in B. sumensis Belemnite Zone of NW Europe; but Voight had lower. DASH CC24 zone boundary: Leg 207 uses this LAD for base-CC24, rather than T. phacelosus ("most workers consider it difficult to distinquish T. orionatus from T. phacelosus, and consider the later species as the senior synonym -- J. Self-Trail", cited in Huber et al’08). SEPM’98 assigned LAD for Boreal as equivalent to 6/10 up in B. grandis Zone of N.Amer., which is nearly same timing. SEPM’98 had assigned LAD for Tethyan at base of Maastrichtian. [GTS04 has used Relative-age to R. levis and as CC24 base.]
