Therefore it is clear that there is a time break here between the Three Forks and Madison limestone. Admitting then the Devonian sea must be taken out of one maps closing the Devonian period. The Madison fauna does not begin with the earliest Kinduworth an faunas than in my Bradfordia at our state. Raymond's came at Brighton Heights, Allegheny Raymond tells me that White has published the finding of Pteremites proliformis in the Pittsburg region. Lee Stevensons last paper on Carbonic, has a long list of Pennsylvanian species from the Pittsburg & western Pa. area. Raymond will make for me 6 or 7 lantern slides or send photos of the Pennsylvanian to show original unemiformities.
