Fossil Friday - deer humerus

One of the collections at WSC comes from the Harveston neighborhood of Murrieta in Riverside County. While this is a fairly small collection, it’s amazingly diverse, with well over a dozen different species of mammals. A group of us have started going through this collection to document it. One of the Harveston specimens is a small deer, probably the genus Odocoileus. The element above is the distal end of the humerus. Modern Odocoileus includes the mule deer O. hemionius and the smaller white-tailed deer O. virginianus. Interestingly, the Harveston specimen is quite a bit smaller than modern white-tailed deer, even though it’s an adult. We have a few other deer elements from the Harveston material that we’ll have to compare to see if the size difference is consistent.
