  1. Crinoids: These fossils are part of the stems of an animal related to starfish. They look like small disks with holes through them and are quite abundant in the area.
  2. Favosites (Honeycomb Corals): These fossils consist of closely grouped calcitic tubes resembling honeycomb. The pattern is smaller than that of a Petoskey Stone and looks more like lace.
  3. Petoskey Stones: These fossils are from an extinct coral that lived 380 million years ago. They have six-sided corallites and are polished by the waves and sand.
  4. Rugosa (Horn Corals): These fossils are pieces of coral with a unique horn-like shape.
  5. Halysites: These fossils are formed from interlocking strings of tiny chains.

Tips for Successful Fossil Hunting

  1. Look for less popular beaches: Avoid crowded areas to increase your chances of finding fossils.
  2. Avoid maintained beaches: These beaches may have stones removed as part of cleaning, reducing the likelihood of finding fossils.
  3. Be prepared to walk: Some beaches may require walking long distances to find fossil-rich areas.
  4. Look closely: Many fossils are small, so pay attention to details.
  5. Go after wind storms: These storms can bring new fossils to the surface, making them easier to find.
  6. Hunt after rain: Wet conditions make it easier to identify fossils.
  7. Bring a bucket or bag: Collect your finds in a container to keep them organized.

Important Considerations

  1. National Shoreline and State Parks: It is illegal to remove stones from National Shorelines, and there are limits to the amount you can collect from State Parks (DNR rules).
  2. Respect the Environment: Always strive to leave the shoreline in better condition than you found it, and dispose of any trash you encounter.

By following these tips and visiting the right beaches, you can have a successful and enjoyable fossil hunting experience on Lake Michigan. Remember to respect the natural environment and follow all applicable regulations to ensure the preservation of these precious geological treasures for generations to come.
