Typical Ordovician fossils
of this section, as stated by Cruse. Saw
some large spirifera on the side of D. corn-
crenatus but are D. crenatus.
Below no.1 it is 180' below to
the new coal outcrop where the beds
dip about 100 while at the next out-
crop they dip about 20 to 25 degrees. This
exposes shor about 30 feet of massive
gray to blue impure limestone with
syngenic vertical joints).
In the maculiforma zone the fossils
are most common in the lower half. D.
maculiforma fails in the upper third where
E. crenatus is most abundant. D. crenatus
gets through.
