1.7" Rare Stellarocrinus Crinoid - Pontiac, Illinois

 
This is a detailed Stellarocrinus virgilensis crinoid from the Bond Formation near Pontiac, Illinois. It's wonderfully preserved, very 3D. It was cleaned under microscope using air abrasives.

Crinoids, sometimes commonly referred to as sea lilies, are animals, not plants. They are echinoderms related to starfish, sea urchins, and brittle stars. Many crinoid traits are like other members of their phylum; such traits include tube feet, radial symmetry, a water vascular system, and appendages in multiples of five (pentameral). They first appeared in the Ordovician (488 million years ago) and some species are still alive today.
