We have a change pace for this week's Fossil Friday. How about a Megistocrinus crinoid from Alpena, Michigan. The Alpena Limestone dates to the Middle Devonian. Crinoids are echinoderms and are related to starfish, sea urchins, and brittle stars. This is a fossilized calyx, which is the top part of the crinoid.
This gorgeous specimen is part of ESCONI member Becky Monroe's collection. You may remember her Mazon Creek shrimp just a few weeks ago in Fossil Friday #128. Thanks for sharing photos of this beautiful fossil! She found it along some railroad tracks in Michigan... that is some luck. You have a great eye!
