Crawfordsville,
Indiana
Description:
Well-preserved example of the Cladid crinoid Sarocrinus varsovensis
(Family Zeacrinitidae), The crinoid is very three-dimensional in aspect,
with preservation of the fine pinnules quite evident. This is a fine
example of the variety of diverse crinoids to be found in the Crawfordsville
deposits. This particular example has much of the stem attached, and
shows the cirri which served as a root system (an individual rootlet
is termed a cirrus), a system that reminds some of the roots of the
mangrove. This is a fine specimen that would be a welcome addition
to any collection of crinoids from Crawfordsville. |
