Polypora sp., from here.

Belongs within: Cryptostomata.
Contains: Fenestellidae.

The Fenestrata are a group of bryozoans known from the Early Ordovician to the Permian. Fenestrates have zoaria arranged in a lacy network with short autozooids on one side of the zoarium, often with a hemiseptum at the base (Prothero 1998).
