| "a uniformly muddy, fine-grained sublitharenite" (Gunnell and Bartels 1999) | sec 8 T 7S R 25E: Van Houten 1945 same as the "Green River" fauna of Burke 1935 and Kay 1957 according to Remy 1992 there is an Ar-Ar date of 47.2 Ma on the "curly tuff... between the S1 marker unit and the Magohany oil shale bed" (S1 unit is lower); because the fauna is from "82 m below" the shale and the date is interpreted by Remy as Uintan, I assume it is too young for use as a calibration point "Class 1" reliability K-Ar date of 44.8 (= 46.0) +/- 0.9 Ma (Mauger 1977) for the Wavy Tuff is definitely too young for use as the tuff is 20 ft above the Mahogany Oil Shale; Wavy Tuff redated at 42.3 +/- 2.0 (FT on zircon) by Bryant et al. 1989 original list repeated almost without modification by Gunnell and Bartels 1999 Black and Sutton list the following: Thisbemys corrugatus "Leptotomus bridgerensis" falls in the Parachute Creek Mbr. sensu Roehloer 1992 early Bridgerian the record of Apatemys hendryi reported by Robinson 1966b is omitted without comment by K & S |
