Summary:

Megafossils in Bateman Formation are rare but late middle to early late Eocene age is indicated by stratigraphic position. Microfossils (foraminifers) were reported by Bird (written commun, June 20, 1967) from beds along ridge east of Ivers Peak. Microfauna indicated late Ulatisian age and deposition at shelf depths, probably between 200 and 600 ft.
