Submitter notes: Collected in 1994, Ken had many years to enjoy this wonderful example of Megistocrinus before he died a few years ago. We collected this at Partridge Point in Alpena and the crinoid was completely covered with bryozoans that can still be seen covering the plate. Ken, at the time, was not optimistic about how this would turn out and until it was cleaned by Scott Vergiels, he did not know what a treasure he had.

Photo title: This magnificent complete crinoid was the pride of Ken Dobson's collection
