Taxonomic list
presumably includes BUNM-77-183 of Tsentas 1981
clearly includes list of Tsentas 1981, despite lack of explicit discussion; includes all Pantolambda Zone taxa mentioned by Lindsay et al. 1978, 1981
two BUNM sites are the same
although Williamson 1996 reports specimen counts for Tsentas Quarry, these apply only to therians
normal polarity, correlated with 27N on basis of biochronology, but there is no independent tie point
