Fossil Friday – mammoth jaw

Most of the current collections growth at the Western Science Center comes in the form of mitigation projects, fossils and artifacts that are recovered during various construction projects. Most of the projects that have come to us are from Riverside County, but we’re increasingly starting to bring in material from other areas. Continue reading

Fossil Friday – proboscidean ulna


Over the last few weeks we’ve started pulling a lot of mastodon material from the collections (more on that in a future post). Some of the bones that are turning up are pretty interesting. Continue reading

Fossil Friday – possible mastodon bones

A common theme on this blog is that we can often get a lot of information from very incomplete material. Even so, as a general rule, the more remains we have from a given fossil organism, the more we can say about it. But sometimes we can have multiple bones, and even something as basic as a species identification can be elusive. Continue reading

Fossil Friday – mammoth tooth

With the influence of Max Mastodon, Diamond Valley Lake mammoths sometimes get short shrift around here. But while DVL mammoths are not nearly as common as mastodons, there is still plenty of interesting mammoth material. Continue reading

Fossil Friday – Xena the Mammoth’s femur

Mastodons were the most common proboscideans in Diamond Valley, but they weren’t the only ones there. Columbian mammoths (Mammuthus columbi) were also present, although in much smaller numbers. The most complete Columbian mammoth from DVL is Xena, whose partial skeleton is on permanent exhibit at the Western Science Center. Continue reading

Fossil Friday – Stories from Bones exhibit

For Fossil Friday this week, I want to highlight Western Science Center’s new exhibit “Stories from Bones”, which opens tomorrow. Continue reading

Fossil Friday – mammoth molar

After a few weeks of focusing on mastodon remains, it’s worth remembering that there were two different species of proboscideans at Diamond Valley Lake. While mastodon remains are quite common, Columbian mammoths (Mammuthus columbi) were also present. Continue reading

Fossil Friday – Xena the mammoth’s tusks

“Xena” is the most complete Columbian mammoth specimen recovered from Diamond Valley Lake, including a nearly perfect skull and lots of postcranial material. Both of Xena’s tusks were also recovered, and are on display with the rest of her skeleton at the Western Science Center. Continue reading

Fossil Friday – tusk fragment


One of the prominent features of modern elephants are tusks, which are greatly enlarged upper incisor teeth. The presence of tusks is shared with most of the elephants’ extinct proboscidean relatives, including mammoths and mastodons.

Fossil Friday – mammoth jaw

2014-09-19aIt’s Fossil Friday, and in what I intend to be a regular feature we’ll look at different specimens in the Western Science Center collection. To kick off, we’ll examine a mammoth jaw to show that not not everything in the Valley of the Mastodons is a mastodon! Continue reading
