商品簡介
The fossils of Anza-Borrego include leaf impressions, shells, bones, teeth, and animal tracks. This record of more than 550 types of fossil plants and animals ranges from microscopic pollen and water fleas to walrus bones and mammoth skeletons. The fossils have been the focus of ongoing research, study, and interpretation since the mid-1850s. Extensive collections from the Imperial Valley College Museum and the Natural History Museum of Los Angeles County now reside in California State Park's Colorado Desert District Stout Research Center in Borrego Springs. The results of the past several decades of study by leading researchers from across the nation can now be seen in this comprehensive work.
