base notes					comp notes	A. hypselum zone is divided into two subzones of nearly equal duration (top 45% = barrense TAsZ & bottom 55% = hypselum TAsZ) on the spreadsheet but not on TSC / this compilation where there is just the hypselum TAsZ). AND the ages are based on a cyclostrat derived zone length of 1.6Ma vs 2.02 zone length based on age from top bifurcatus to base bimammatum. Combined these mean the pup need to be multiplied by 0.55 x (1.6/2.02) =0.4356. JRY In this case pup has been changed from 0.48 to 0.209
