2.7" Rare, Ordovician Starfish (Urasterella) Fossil - Oklahoma

This is a very rare, 2.7" wide Middle Ordovician, fossil starfish (Urasterella sp) from the Bromide Formation of Oklahoma. It is part of a pocket that was collected some time ago (I believe decades) and very little starfish material has been recovered outside of this pocket.

While the species was not described the occurence of these starfish was mentioned in the paper linked below.
