[edit]

The NALMA list shows the Puercan interval beginning at 66.5 Mya instead of the customary 65.5 Mya corresponding to the Iridium Anomaly. Is this a typo? A holdover from original 1941 establishment of the NALMA before the Iridium Anomaly was discovered? In either case, it should be made consistent with current NALMA definitions, whatever they are.
