Paleontology
A commonly found and easily identifed part of a mammal skeleton is the head of the femur. This is visible in the Pacific mastodon femur below, as the large knob at the upper right end of the bone: The femoral head is a large hemispherical mass that generally sits on

Later this year we're going to open a new permanent exhibit at Western Science Center featuring Ice Age fossils from Riverside County. While the largest single fossil collection at WSC is from Diamond Valley Lake, we are the fossil repository for the entire county and hold collections from

As I've mentioned in prior posts, many of the Western Science Center's fossils were discovered during construction projects. Often the first indication that a fossil is present is when a bulldozer or other piece of machinery cuts through a bone, at which point the mitigation paleontologists
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&

Before coming to the Western Science Center I worked at the Virginia Museum of Natural History as Curator of Paleontology. My primary field site during that time was the Carmel Church Quarry in eastern Virginia, a remarkable location with multiple fossiliferous beds spanning 60 million years of time. During my

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
