Fossil range Age.—Ewing (1981, p. 1471) cited ages of 52 6 2, 51 6 2, and 49 6 2 Ma for ash beds in the McAbee beds as determined by Hills and Baadsgaard (1967). The oldest and youngest ages were based upon analysis of plagioclase in ash beds 1 and 2; the intermediate age was based upon analysis of biotite from ash bed 2. These ages place the McAbee beds within the late Ypresian (early Eocene) (Gradstein and Ogg, 2004). [details]
