 Description:
This fossil association is quite distinctive in that the crinoids
found are in a superb state of preservation and can be seen on
BOTH SIDES
of the plaque. The larger crinoid is an excellent Taxocrinus colletti
with the many curled arms and long stem in a beautiful state of
preservation. As an additional attraction, the second crinoid is
an example of the rare Aulocrinus bellus which shows the distinctive
J-shaped anal tube on the main side and more detail to the cup
and attached stem on the reverse. Echinoderms typically disarticulate
rapidly after death, so the have not one but two in such a great
state of preservation is most unusual, certainly deserving the
appellation MUSUEM QUALITY. It is easy to see why Crawfordsville
is world-renowned for the quality of preservation of its wonderful
crinoid fauna.
