Name: Scytalocrinus disparilis (Family Scytalocrinidae)
Age: Lower Mississippian Osagean Stage
Size (25.4 mm = 1 inch): Crown: 22 mm long by 10 mm wide stem: 45 mm on a 75 mm by 52 mm matrix
Location: 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. |
