1921-1927: The Campanile opens its doors to thousands more fossils, this time from the McKittrick tar pits in San Joaquin Valley. The 9,000-to-13,000-year-old objects excavated by the UC Museum of Paleontology include the remains of dire wolves, coyotes, camels, mammoths, many kinds of birds and small rodents, wood and seeds from juniper and pine trees, and diverse insects. UC Berkeley has the first fossil record of McKittrick tar pit materials from the end of the Ice Age; the Los Angeles County Museum follows.
