Yesterday's Animals of the San Joaquin

Abstract

One need not explore far back in earth history, certainly no farther than the Glacial Period or the geologic yesterday, to apprehend the great change which has occurred in the life of the San Joaquin plain with the passage of time. Fortunately for the student of this intriguing chapter in the geological story of California, tar seeps in the vicinity of McKittrick, west of Bakersfield, have preserved animals and plants of the Ice Age in much the same manner as the famous Rancho La Brea deposits have their ancient life record in southern California.
