It is unusual to find coral fossils at the Deep Springs Road quarry as the rock is a limy siltstone. One would not think a coral like Favosites hamiltoniae would like the muddier water. Perhaps it was washed in during a storm or records a less muddy interval that allowed the coral to thrive. In either case this is a cool specimen for the rarity of it being found at this location. It appears to be a part of a larger, branching body and I only found a part of it. There is still quite a bit or rock covering the specimen and filling in the corallites.
This specimen was found at a borrow pit on Deep Springs Road in Madison County, NY which exposes the Windom shale member of
the Moscow formation (middle Devonian in age, Givetian stage.)
