Submitter notes: The checklist of fossils from the area lists four different species of Fenestella from the Hungry Hollow mb. Most bryozoa are difficult to identify and require thin sectioning for positive I.D. I can identify only by sight. This specimen is 40mm high and 35mm wide and rests on a slab 42mm x 60mm.
