interval_notes:	DASHED -- Base of T. praeticinensis foraminifer subzone = 17 long-eccentricity cycles below top Albian (6.8 myr) => 106.4 Ma. The duration is 3.2 myr, nearly the same as the 3.3 myr used in Leckie et al. (2002). (NOTE -- Leckie et al., 2002, define the T. praeticinensis foraminifer subzone as the base of B. breggiensis Zone, in turn defined by the base of that species; however, the actual FAD of T. praeticinensis is below/older than the base of B. breggiensis according to both Leckie et al., 2002, and Hardenbol et al., 1998. Because Premoli Silva is a co-author on both the Leckie et al., 2002 paper and on the Piobbico cycle stratigraphy paper, I?m assuming that the T. praeticinensis subzone is defined as base of B. breggiensis for this scaling. In contrast, the zonal schemes of Hardenbol et al., 1998, and Bellier et al., 2000, do not have a B. breggiensis zone, but define the base of T. praeticinensis zone by the first occurrence of the name species. What a mess.) (primary control on Albian scale!)
