Taxonomic list comments:immediately overlies "Marker A Coal"identical SCLF AA dates of 78.2 +/- 0.2 Ma (biotite and sanidine) for ash 27 m above coal: Goodwin and Deino 1989; this is redundant with date for lower ash that calibrates Put's Plunder because Makela's French is closer to the lower ashNISP 109
