Excerpt from Fossil Fishes of Diatom Beds of Lompoc, California Since that time, through the courtesy of Mr. Arthur H. Krieger, director of the Celite Products Company, and his assistants, Messrs. Ed ward Porteous and Edward B. Starr, Dr. Gilbert and Dr. Jordan have successively Visited these deposits, making extensive collections. Still later, Mr. Willard J. Classen, a student in Geology at Stanford University, through the kindly interest Of Mr. Timothy Hopkins, has spent some time there securing fossil fishes for Stanford University. A large collection of fish has been Obtained, this forming the basis of the present paper. The Lompoc deposit itself is wholly unique. It lies in Santa Barbara County, California, within an angle on the north side of the Sierra Santa Ynez, a range composed mainly of Miocene sandstones and shales. This angle or ancient bay covers about four square miles. In this space a continuous and almost uniform mass of diatoms has been deposited, to the maximum depth of feet. The erosion of a stream on the west side has cut this deposit through to its bottom of yellowish sandstone. Over most of this space, the diatom deposits come to the surface, but in places the mass is overlaid by a coarse, hard breccia or conglomerate, containing many bones of whales, and occasionally teeth of sharks. On the extreme west, it is overlaid by limestone in which a species of Pecten is very abundant. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
