Fenestrapora
Fenestrapora is an extinct genus of bryozoans of the family Semicosciniidae that lived during the Devonian period. Its colonies have a net-like structure, shaped into a flaring funnel. It is distinct from most other fenestrate bryozoans due to its aviculomorphs, structures that are thought to have had the function of cleaning or defense. References
