There are many places to see some of the fossils and artifacts excavated in Orange County, and to learn more about the past. A permanent paleontology museum at Ralph B. Clark Regional Park showcases many Pleistocene fossils, including saber-toothed cats and giant ground sloths, and the amazing 30 foot skeleton of a prehistoric whale.  Other exhibits in the County are rotating, so check back often for an exhibit in your neighborhood.

Over the past million years or so, the area that has become Clark Regional Park has changed from a marine environment to a terrestrial environment. The park's rich fossil beds were revealed when the California Division of Highways excavated sand and gravel from the site for use in construction of the Santa Ana and Riverside Freeways from 1956 to 1973. Orange County wasn't always populated by nice, friendly people. The original residents were a bit wilder. Mammoths, ring-tailed cats, giant ground sloths, and a unique type of ancient llama lived in this area. Clark Park's nationally recognized Interpretive Center is home to one of the more significant fossil museums in southern California. The recently renoved display contains fossils from the park and surrounging Coyote Hills, and throughout Orange County. There is also a working paleontological laboratory on-site that can be viewed by visitors.

Fossil excavated from construction of the Kaiser Permanante medical office in Foothill Ranch are displayed there, including a whale, a dolphin, and a Pacific Loon from seas that covered the area five million years ago.
The City of Laguna Hills Community Center and Sports Complex were built on one of the richest fossil sites in the United States. In 1996 this wealth of fossil resources was chosen as a theme around which the Community Center and the Prehistoric Playground were designed.
The recently renovated and reopened Age of Mammals hall is a spectacular journey through the last 65 million years of Earth history with a focus on mammals and their adaptation to the environment.  L.A.C.N.H.M. contains a large collection of Orange County fossils, including the strange animal Paleoparadoxia on the second floor of the exhibit.  Not to be missed!
