	Submitted on 2007-03-09 by David Thompson Location (approximate): Alpena, Alpena, MI Strat unit: Four Mile Dam formation Submitter notes: This example of Megistocrinus rugosus crinoid caylx shows how at times mineral replacement can be of a rich red Calcite, making a nice fossil more attractive. This was collected at a bioherm or fossil 'reef' in a quarry. This shows the stem base, the upper tegman is complete also.
