Science
As we prepare our new exhibit, we’re drawing on collections from Riverside County that have mostly been recovered by mitigation companies. These companies generally do a great job of documenting and identifying specimens, but there are outliers. Unfortunately we have acquired a number of specimens that weren’t prepared
Paleontology
As we prepare our new exhibit on Ice Age fossils from Riverside County, one of the things we chose as a focus was to highlight the diversity of these deposits. To that end we've specifically looked for fossils that represent a broad range of species. Over a year
Mammoth
Western Science Center serves as a fossil repository for several state and federal agencies, including the National Park Service. Related to that responsibility, a couple of times a year we send a team under permit to Joshua Tree National Park to collect fossils that have naturally weathered out of the
Osteology
Many of the fossils housed at Western Science Center were recovered by paleontology mitigation companies from construction projects. This is a common and convenient arrangement in California that results in many more fossils being saved. (I've worked as a paleontologist in other states that do not have California&
Paleontology
Later this year Western Science Center will be opening a new permanent exhibit (more on that in a future post). One of the highlighted specimens in this exhibit will be the skull of Harvey the Mammoth. Like many of WSC's specimens, Harvey was discovered during a construction project,
Fossils
Shortly before the holidays, our curator Andrew McDonald and I were looking through one of our collections cabinets for a particular specimen from Murrieta, California. In the process we stumbled across a fragment of another tooth, recently prepared by a volunteer but not yet catalogued. Even though it was incomplete,
Snails
In our current exhibit "Life in the Slow Lane" one of the displays features fossil snails recovered from Pleistocene sediments during the Diamond Valley Lake excavation. Of the roughly 100,000 fossils recovered from DVL, over 4,000 were snails. These were pretty much all very small freshwater
Mastodon
As I mentioned last week, many of the Western Science Center's fossils are actually recovered by paleontology mitigation companies, thanks to California's robust protections for fossil resources. Most of these companies are highly skilled and professional and do a great job recovering the specimens and their
Paleontology
California is unusual among U.S. states in having relatively robust protections for fossil resources, even when they are not on public lands (most states have none at all). As part of the permitting process for real estate development, developers are supposed to provide for the collection and preservation of
Miocene
Besides the proboscidean tooth I talked about last week, our recent excavation in the Miocene Cajon Valley Formation turned up other interesting remains. Because these sediments were deposited in a fast-flowing stream bed, we don't typically find skeletons. Most of the identifiable remains are isolated teeth, and
Paleontology
Last Monday, several of our staff members visited a fossil locality on National Forest Service land in San Bernardino County that we've been excavating for a number of years under an NFS permit. The deposit exposes a conglomerate of the Cajon Valley Formation, which is middle Miocene in
