摘要
This paper is the first to discuss in general the occurrences of fossil fish in California and to consider their significance in the study of geological problems relating to the marine Tertiary of the Pacific Coast. Fossil fish are abundantly represented in many horizons of the California Tertiary. However, the preservation of more or less complete fish is restricted mainly to the Upper Miocene, and only these forms are considered in the present study. In earlier epochs of the Tertiary, remains of fossil fish are represented principally and not sparingly by scales or single bones only. Study of these earlier occurrences of fish fossils remains in a beginning stage but promises to give valuable additional information to our present knowledge.
