Sieberella romingeri, bryozoa 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.
