Traverse formation |
David Thompson |

Submitted on 2008-02-17 by David Thompson
Location (approximate): Alpena, Alpena, MI
Strat unit: Traverse formation
Submitter notes: This is one of three views of this brachiopod from the Genshaw formation in the Lafarge Quarry of Alpena. This 'old' brachiopod is encrusted with bryozoan and some few Aulopora. Anything that was hard and still for very long had something
living on it. I have collected very few of these brachiopods that were not damaged or missing valves.
