It came from... Canada!

Quite a long time ago we visited my Canadian cousin and her husband in Little Current, Manitoulin Island. Although the island is in Lake Huron, it has some splendid marine fossil beds from the deep past. These are the remains of an ancient crinoid.
Crinoids are marine animals that make up the Crinoidea, one of the classes of the phylum Echinodermata. Crinoids which, in their adult form, are attached to the sea bottom by a stalk are commonly called sea lilies.Now, there are only about 600 living species of crinoid, but the class was much more abundant and diverse in the past. The remains in the photograph are about 400 million years old.
