Williams and I spent the day at the
Clay Cliffs to study the lower beds, the
so-called "Eden Beds".
The Clay Cliff is probably very 200 feet high
with at least 12 feet more of Richmond above,

lower 50 feet or so and it may be 70 feet
have no Richmond fossils. Our collecting
of the day was in the lower 30 feet of these
lower beds of the Clay Cliff which we exposed
at about 1/4 mile south of the cliff.
We did not see a single diagnostic
fossil of the Richmond in these lower 30 feet

are common are Rafirostrum squamula
and a large Plec. delicatus. Rarer forms
are Heterotilla occidentalis, Dal, nearest to
