base notes	DASHED: Assemblage zone (all listed species span the same interval, according to Ross-Ross'95) assigned as equivalent to the one with E. linearis in Davydov'96 chart. However, Ross-Ross implies span is approximately Sakmarian, therefore I've put near base-Sakmarian (base of Cf7). However, logic of placement of that zone with Pseudofusulina concavutus zone is not indicated.				comp notes
