Blastoids!
These Pentremites are often called 'Blastoids' . They are extinct echinoderms with living
relatives including; starfish, sea cucumbers, sea urchins and brittle stars. They attached
themselves to the bottom of the sea floor with thin stems. Mississippian in age, they
lived 320 to 360 million years ago. They have been beautifully prepped and many of
them are accompanied by other fossils on the same matrix.
