 Description:
This crinoid is in a most unusual orientation. They are believed
to have lain at the sea floor curled much of the time, unrolling
to filter feed when conditions were right. The proximal end of
the stem shows the cirri by which the crinoid remained anchored
to the seafloor. The crinoid is found in association with a partial
Playceras gastropod, several byozoans , and numerous other fragments
of sea life making for a fine association plaque. |
