 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. Nearly all of these crinoids are
found curled; this one must have been overcome so quickly when it
was engulfed by a turbidity flow that it did not have a chance to
assume its normal posture, giving you a unique example of this unusual
taxon. The stem shows the cirri by which the crinoid remained anchored
to the seafloor. |
