Submitter notes: This a very nice specimen showing a crinoid crown with two gastropods attached. The spines on the crinoid calyx are still attached. The very long spines of the gastropods are still in place. In addition, there is bryozoan in place on the gastropod (photo is in next datapoint entry). This specimen is 14 cm across from arm tip to arm tip.
