interval_notes:	DASHED -- Base of former H. planispira foraminifer zone (assumed "LAD" of T. bejaouaensis, now P. eubejaouaensis" definition is used by them?) is 31.4 long-eccentricity cycles below top of Albian (Huang et al, 2010; and Wendy Zhang, 2019) at Piobbico. Brian Huber (to J.Ogg; 15Aug11 "Note that there is no longer a planispira zone because true planispira did not evolve until the late Albian!") Calibrations of other authors are inconsistent -- the base of the H. planispira Zone is placed ABOVE base of P. columnata in Leckie et al. (2002), middle of H.jacobi ammonite zone of Late Aptian (Herle et al., 2004) and much higher as the middle of Lower Albian by Bellier et al. (2000) -- and other assignments are briefly reviewed in Petrizzo et al. (Newsletters of Stratigraphy; in press 2011). However, Hardenbol et al. (1998) place the FAD of H. planispira below the FAD of P. columnata, as is indicated at Piobbico and at the reference sections in SE France; thereforehad assigned as 50% up in H. jacobi Zone. "Gap zone" (LAD at base; FAD at top)
