Scytalocrinus Crawfordsville Crinoid with Long Stem

Scytalocrinus disparilis

Family Scytalocrinidae

Geologic Time: Lower Mississippian Osagean Stage

Size: Crown: 22 mm long by 10 mm wide stem

Fossil Site: Crawfordsville, Indiana

Description: The crinoid is a fine example of an Inadunate Cladid crinoid (Family Scytalocrinidae) known as Scytalocrinus disparilis from the famous Crawfordsville crinoid beds. Preservation on this specimen is remarkably complete, down to the fine pinnules on the arms. What is most interesting about this specimen is that some of the cirri which served as a holdfast in the distalmost portion of the stem can be seen. This specimen is well centered on its siltstone matrix, and would make a fine example of the type in any collection.
