With many fossils, particularly vertebrates, small fragments can sometimes be very informative and justify close scrutiny. That was the case with a pair of associated bones from Diamond Valley Lake. One of the fragments, shown above, includes the occipital condyles that form the articulation between the skull and the first vertebra. The condyles sit on either side of the foramen magnum, the opening through which the spinal cord passes. Continue reading

During last week’s Valley of the Mastodons events, museum supporter Doug Shore donated a collection of invertebrate and plant fossils to Western Science Center.  Continue reading

Fossil Friday – mastodon tusks

IMG_5348In three days scientists start arriving in Hemet for the Valley of the Mastodons symposium, and we’re one week from the opening of the associated Valley of the Mastodons exhibit. As a result, I’m a little swamped, and today’s Fossil Friday post will have to be brief. Continue reading
