Abstract
MANY attempts have been made to establish better correlations between the Miocene marine geological strata of California and those of Europe and tropical regions. The two chief difficulties have been that many of the important zonal fossils of one region are absent in other regions, and even those important faunal indices that are common to the different areas have differential ranges when compared with one another. Discovery of the Catapsydrax stainforthi planktonic foraminiferal fauna on Erben Guyot1—a guyot located about 800 miles west of San Diego—made it possible to correlate these planktonic fossils with the standard planktonic zones of tropical areas but unfortunately not with the standard California Miocene Stages of Kleinpell2.
