Fossil Hunting In Wisconsin

Where can I find fossils in Wisconsin?

Be courteous when searching for fossils. If you plan to search private property, always ask for permission from the land owner first. Keep in mind that Colossal Fossils Inc. is not responsible for determining whether or not permission is required.

Use appropriate safety gear. Many areas could have hazards like falling rocks. Hard hats and safety glasses may be appropriate.

 Check out this Colossal Fossils video:

• Eau Claire County: Outcrops on Mt. Washington are rich in brachiopods and trilobites.
• Door County: Look amongst the rocks on the beach along the shores of Kangaroo Lake. Corals are extremely plentiful.
• Grant County: Ordovician fossils are prevalent on highways both south and west of Fennimore. Check all the rock cuts on Hwy 61 between Dickeyville and Fennimore.
  
• Green County: Trilobites and gastropods can be found in a road cut west of junction WI92 & WI69.
• Monroe County: 8 miles west of Tomah, in road cuts along Highway 16, look for trilobites
• Pierce County: Check the backroads for any roadcuts south of Ellsworth.  Roadcuts along County Road J also contain brachiopods.
  
• Trempeleau County: Fossils can be found near the town of Trempeleau and north of Whitehall along many road cuts.
• Shawano County: A roadcut along Highway 29 East just a few miles outside the city of Shawano shows evidence of stromatolites from a rock formation known as the Prairie du Chien group.  Lots of traffic, be careful!!!
