Miocene Fishes of Southern California

Parts I to III of the paper describe faunas of fossil fish from different horizons of the Los Angeles Basin. Part I. Collections of fish fossils were made at a number of localities on the west side of Sepulveda Canyon, Santa Monica Mountains, California. The fishes occur in hard siliceous sandstone and shale of the lower Modelo formation (Upper Miocene). Eighteen families and twenty genera are represented. The assemblage suggests a marine neritic subtropical fauna, living at a depth of 100 to 200 m. Part II. The diatomaceous shale of the Upper Modelo formation yielded an abundance of fossil fish...
