Below is an example of a Box Crinoid I was lucky to find in 2017 with the Cedar Valley Rock and Mineral Society in 2017. This quarry can produce Devonian Phacops, Greenops, Crinoids and Fish parts, besides lots of brachiopods . Been going here and the Conklin quarries for close to a decade. Finally found a complete Crinoid. This one is a Camerate Crinoid, more common name Box Crinoid.
