Western Science Center in Hemet Receives Fossil Whale

HEMET –The largest natural history museum in Riverside County has a new arrival – the Western Science Center has received a fossil whale from Los Angeles County-based mitigation company Paleo Solutions, Inc.
In September 2015, a Paleo Solutions’ paleontologist watching construction excavations for the Polo Ranch housing development in Scott’s Valley, California, spotted a bone that was unearthed by heavy equipment. More bones were exposed, and the bone was identified as an extinct species of baleen whale. The specimen is approximately 3-5 million years old.

Several jackets of material were delivered to the museum on Friday, June 22nd, and the largest of those jackets will be on public display outside of the museum’s main building near the Simulated Dig Site.
Western Science Center staff and volunteers will immediately begin the lengthy process of preparing the whale out of the jacket and removing the surrounding sediment, which visitors will be able to observe as part of their regular museum admission.

Visitors to the Western Science Center will also have the opportunity to put forward their family-friendly ideas for the new arrival’s name, which will then be voted on by WSC staff and announced on July 11th. Suggestions can be submitted either online at or at the admissions desk. “Whales have been part of California’s ecosystems for millions of years; we’re excited to give our visitors the chance to give their new neighbor a name!” says Marketing & Events Specialist Brittney Stoneburg.

The recovery and permanent preservation of this exciting fossil discovery could not have been made possible without the hard work and dedication of Paleo Solutions’ salvage and laboratory staff; support and assistance of the Lennar Corporation, Independent Construction Company, Albion Environmental, and City of Scotts Valley; and vision and commitment of the Western Science Center staff and volunteers.

Mastodons to the Max Event Celebrates Mastodon Exhibit at the Western Science Center

HEMET – A new year offers Western Science Center visitors a new opportunity to learn about the prehistoric elephant-like creatures that once roamed the Inland Empire! The Western Science Center kicks off the second half of the Valley of the Mastodons exhibit with a new event on January 20, 2018.

Valley of the Mastodons, the largest exhibit of mastodons ever developed,started out as a scientific workshop hosted by the Western Science Center in August 2017. Scientists and science writers from across North America came to Hemet to study the museum’s collections and make contributions to the Valley of the Mastodons exhibit, which is now open to the public through May 2018. Through this conference and exhibit, the Western Science Center has given visitors a window into the scientific process and into the fossil record of mastodons.

Visitors will have a chance to catch up with some of the researchers who participated in the Valley of the Mastodons conference this past August, who, along with other scientists, will be Skyping into the museum theater throughout the day to give presentations on their research.

“Mastodons are an iconic American Ice Age fossil,” says Dr. Alton Dooley, Executive Director of the Western Science Center. “While the Valley of the Mastodons exhibit focuses on California mastodons, our knowledge comes from workers and specimens all over the world. This event will give visitors a chance to see examples of other mastodons from across the country.”

In addition, young visitors can explore the Pleistocene through the museum’s Valley of the Mastodons scavenger hunt and take home a miniature 3D print of one of the exhibit’s mastodons. Other hands-on activities will be available, such as coloring pages and more. Museum staff will be preparing mastodon fossils and answering visitor questions at the museum’s new Exploration Station in the main exhibit hall.

A free print of the Valley of the Mastodons exhibit mural, signed by paleoartist Brian Engh, will also be raffled off to one randomly chosen user who uses the #ValleyoftheMastodons hashtag on Instagram, Twitter, or Facebook. More information can be found at

The event is on January 20, 2018 from 10:30AM – 4PM. Admission is $8.00 for adults, $6.50 for seniors 62+, $6.50 for students 13-22 w/ID, $6.00 for youth 5-12, under 4 years old is free, and Active Military (individual) w/ID is free. Admission to the museum is included in the ticket price. WSC members can attend for free. All proceeds from the event benefit museum exhibits and programs.

HEMET – Mastodons once roamed Diamond Valley Lake – this summer, they’re coming back! The Western Science Center, Riverside County’s largest natural history museum, is announcing the opening of a new exhibit, Valley of the Mastodons, on August 5th, 2017.

Dozens of individual mastodons were found during Metropolitan Water District’s excavation of Diamond Valley Lake; this has earned Hemet the nickname “Valley of the Mastodons”, and many people aren’t aware that these prehistoric relatives of elephants once roamed their backyards.

Valley of the Mastodons will not only be an exhibit, but a workshop where science will be done in real time
in front of the public! Beginning August 2nd and leading up to the exhibit’s opening reception on August 4th, scientists from across the country will be arriving at the Western Science Center to study the mastodons in the museum collections.

“The Western Science Center has an amazing collection of mastodon fossils that I had a brief opportunity to study last summer. While studying them, I began to realize how different they were – in size and shape – from mastodons from other regions of the country,” says Dr. Kathlyn Smith of Georgia Southern University, one of the participating researchers who will be attending the Valley of the Mastodons workshop. “I’m thrilled to find out what new ideas and research opportunities this ‘meeting of the mastodon minds’ will produce, and am delighted to share the research process and interact with members of the public through this exhibit!”

Other participating researchers include Chris Widga (East Tennessee University), Jeremy Green (Kent State University), Eric Scott (Cogstone Resource Management), Gregory Smith (Vanderbilt University), Dr. Bernard Means (Virginia Commonwealth University), Kathleen Springer (USGS), and Dr. Grant Zazula (Yukon Department of Tourism and Culture). The exhibit will also feature artwork by paleoartist Brian Engh.

Members of the public will be able to talk with the scientists during museum hours; local students will be invited to the Valley of the Mastodons workshop to hear lectures from the researchers.

“The Diamond Valley Lake fossils are having a major impact on our understanding of Ice Age California, and mastodons are a big part of that story,” says Dr. Alton Dooley, Executive Director of the Western Science Center. “WSC’s mastodon collection is the largest on the west coast and one of the largest in North America, and we’re proud to have this opportunity to advance scientific and public knowledge of these interesting animals.”

Valley of the Mastodons is sponsored in part by Bone Clones, Inc., Golden Village Palms RV Resort, Abbott Vascular, and California Imaging & Diagnostics. A special exhibit reception for WSC members and VIPs will be held on August 4th at 5:30 PM; light refreshments will be served. The exhibit will open to the public August 5th.

Admission to the Western Science Center is $8.00 for adults, $6.50 for seniors 62+, $6.50 for students 13-22 w/ID, $6.00 for youth 5-12, under 4 years old is free, and Active Military (individual) w/ID is free. Valley of the Mastodons will run until early 2018.
