Description

Middle Ordovician
Verulam Formation
Brechin, Ontario, Canada
143mm slab with 3 and partial Pleurocystites
Echinoderm,

Cyclocystoides is one of those odd animals that has been difficult for paleontologists to assign to a particular group other than that it’s an echinoderm.  Part of it is that it is a rare find, and when you do find it, it tends to be in poor condition.  What they can see, however, are some unique features that don’t make it compare well to other groups.

This association piece has three with a partial cystoid, Pleurocystites.
