Fig. 8. Correlation of Pipestone Springs and Flagstaff Rim upper Eocene lithostratigraphy, and stratigraphic position of tuffs and vertebrate assemblages. → A. Location of Flagstaff Rim (Wyoming) and Pipestone Springs (Montana). B. Pipestone Springs reference section and Flagstaff Rim section showing its lithostratigraphy, and stratigraphic position of tuffs and vertebrate assemblages. Sections are correlated based upon Pipestone Spring's 40Ar/39Ar age of 36.00±0.20 Ma tuff and Flagstaff Rim's Ash B, and on middle Chadronian vertebrate assemblages in the PSMP and between Flagstaff Rim's Ash B to Ash G. 40Ar/39Ar age controls for Pipestone Springs strata are from this study; Flagstaff Rim tuff ages are from Swisher and Prothero (1990), Obradovich et al. (1995), and Sahy et al. (2015) Abbreviations: An, anorthoclase; Bi, biotite; S, sanidine (denote minerals used for single crystal 40Ar/39Ar age analyses of tuffs).
