Two, Rare, British, Silurian Crinoids (Marsupiocrinus)

This is a pair of rare, Silurian, Marsupiocrinus crinoids from Dudley England. There are two crowns on this piece, one on each side of the rock as well as several stem sections. Comes with a display stand.

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.
