Taxonomic list comments:this is Junction sensu stricto underlies Whistler Squat said by Prothero 1996b to be Bridgerian; Figure 2 of Wilson indicates that it is roughly at the level of the Alamo Creek Basalt because both are above the "basal Tertiary conglomerate" and below the "variegated bentonites"; the ACB is dated at 46 Ma (KA), and a tuff just below it at 46.0 +/- 1.0 Ma (KA) and 46.29 +/- 0.05 Ma (AA); latter date seems best the following taxa are from Junction, exact locality unknown: Scenopagus priscus Centetodon pulcher ? Entomolestes sp. Nyctitherium velox cf. Pantolestes sp. |
