This nicely preserved Favosites turbinatus coral that is fairly large with about a 10 cm diameter. The preservation is quite nice and cleaned by early Spring rains. The coral is from the Beechwood Limestone of Jefferson County, Kentucky. Middle Devonian Period is the time frame this colony of animals existed in.
Species was named by Billings in 1859. These corals are found in other areas of North America: Hungary Hollow Formation and Onondaga Limestone of southwestern Ontario; Hamilton Group and Onondaga Limestone of New York; and Bois Blanc Formation and Prout Limestone.
UPDATE: The next two pictures show the coral from side views.
