Abstract
Fossil bones collected in the latest Miocene (= either late Clarendonian or early Hemphillian North American Land IvIammal Age), San Mateo Formation, near Oceanside, San Diego County, California, C. S.A., belong to a single specimen of the genus Makaira, species undetermined, and is part of the San Luis Rey River Local Fauna. For the genus, this represents the fifth discovery in fossil deposits bordering or within the Pacific Ocean region, and the third discovery in southern California, The specimen is within the known geochronological distribution of the genus (Late Miocene to Recent), provides further evidence that the coastal palaeoclimate of southern California was warmer than at present, and indicates that there probably was a deep water, oceanic habitat at or near the depositional site,
