base notes	Microhedbergella rischi:<br>Datum calibration/notes = A secondary marker just above base-Albian (easy to recognize). Huber-Leckie’s estimated 300 kyr interval above LAD of P. eubejaouaensis (used here) [LAD P. eubejaouaensis now = LAD P. rohri]; but Huber (pers. comm., Sept 2011) implied that it should be shorter. "accompanied, within a short stratigraphic thickness, by the extinction of several other Aptian hedbergellids, including Hd. infracretacea, Hd. occulta, Hd. gorbachikae, and Hd. excelsa, as well as Gl. aptiensis. Species diversity is very low," (Huber-Leckie, 2011).				comp notes
