fossils are not very common I obtained Produdus giganteus at all 
these places. The Yeathouse Quarry gives the following section, 
the beds dipping west at about 20'. 
Limestone massive, beds much mottled with 
Produdus giganteus, 50 feet. 
Bluish Limestone with peculiar black inclusions, with 
Produdus giganteus, 30 feet.
