Fossil Friday #311: Dung Beetle Balls from the Oligocene

This is the “Fossil Friday” post #311.  Expect this to be a regular feature of the website.  We will post fossil pictures you send in to esconi.info@gmail.com.  Please include a short description or story.  Check the #FossilFriday Bluesky/Twitter hash tag for contributions from around the world!


Today’s contribution comes from our old friend Ralph Jewell. Back in the 1990s, Ralph was interested in the Oligocene fossils of the Brule Formation, which dates to 34-40 million years ago. This region is sometimes referred to as the White River as the Brule Formation is a member of the White River Group.

Ralph would go out there often. He collected many fossils of Oreodont, early horses, camels, rhinos, and, of course, Nimravids, which is the origin of his handle on The Fossil Forum.

One day, Ralph happened on about 75 fossilized dung beetle balls on private land near Douglas, Wyoming. He sent some to friend and now they are on the website: “Coprolite, A Really Crappy Story” a place dedicated to fossil poop! By the way, there’s also a book!

Ralph sent along some “fresh” photos of some fossilized dung beetle balls in his collection. Thanks for sharing, Ralph!
