Lyropora sp. #2
Paint Creek Group
Vogel School site, near Floraville, Illinois
This is an Extremely Large specimen
In life, fenestrate filled the opening between the "wings"
Reminds me of fenestrate attached to the screw-like axis
of the bryozoan Archimedes.
The bryozoan genera Lyropora and Lyroporidra
(order Fenestrida, family Polyporidae) in Upper Mississippian
(Chesterian) rocks of eastern North America.
