Here is a nice palm sized colony of Favosites hamiltoniae that I found in the Centerfield mbr. of the Ludlowville formation near East Bethany. It is partially replaced by Quartz which is why it has a sort of patchy look on the dorsal surface. Some of the corallites are missing while others have some nice detail preserved of the septal spines.
The Centerfield mbr. of the Ludlowville formation records a portion of the Givetian stage of the Devonian period.
