interval_notes:	’P1a’ is the ’Parvularugoglobigerina eugubina - Subbotina triloculinoides Interval Subzone’ (Berggren et al.,1995), which is an emendation of the former P1a ’Parasubbotina pseudobulloides’ subzone of Berggren & Miller (1988), but the range is essentially identical. Note that both are a "gap" zone (LAD of eugubina to FAD of another marker).

base notes	Defines base of zone P1a. [called ’Globigerina eugubina’ in some older publications] Berggren and Pearson (2005) uses same chron-age calibration as Berggren et al. (1995a): The LAD, defining the top of Zone P-alpha, is near the FAD of P. pseudobulloides; and Berggren et al. (1995a) "admittedly somewhat arbitrarily" placed both events just below the polarity chron C29n/r boundary (p.146) = Chron C29r.95.				comp notes
