Lecture 77a Hyopsodus: Why Common Fossils are Important

I talk about my first science project as a young student on the fossil record of Hyopsodus, a very common fossil, which is found in early Eocene rock layers. Common fossils are important because they allow you to study evolution over long periods of time.

Here is the link to the paper I mentioned:
Burger, B.J. 2008. Evolution’s tempo and mode during the Eocene Epoch: comparison of two long contemporaneous records of the fossil mammal Hyopsodus in the American West; pp. 41-58, in M. Connely (ed.) The Eocene Epic- Life, Death and Conquest in the Early Tertiary the 14th Annual Symposium on Paleontology and Geology at the Tate Museum, Casper College, Casper Wyoming p. 101.
