Aquitanian Planktonic Foraminifera from Erben Guyot

Planktonic foraminifera occur in the limy sediment of a manganese-coated breccia from the top of Erben Guyot, a sunken island which is located about 800 miles west of San Diego, California. The fauna suggests an age of Early Miocene (Aquitanian Stage), which represents an absolute age of more than 25 million years. Bathyal foraminifera in the sample indicate considerable subsidence between the suggested time of truncation (Oligocene) of the seamount and the accumulation of the foraminiferal fauna.
