Taxocrinus and Aulocrinus Crawfordsville CrinoidsDescription: 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.
