among them not common are Phymatostroma
cephal, and many fragments of manor
bedded lll genus that must have been ten
with a mile in length. Richmond fossils
in the Circle.
Taff says continue down to 300 feet.
Conformably but rather sharply follows
upwards?
even
300 feet of Aylran shale that near the bottom
are chocolate colored and
lamar ocellated limestone. Near the base
of this Aylran occur in very large space
Heliographus and rare Climacograptus. There
are shells
green ten foot of Shales, and then
occurs a thin chocolate colored impure
limestone that has the same graptolites and
an abundance of Lingulids, and some
rare small Schizocrania and a large
Lingula.
Hither the shucks are very good of shale.
See these four lots of fossils.
Which refers these Aylran Shales to the
Ordovician but they are clearly better referred to
the Richmondian, as as soon the upper
300 feet of the Circle. The Richmondian is
here therefore about 600 feet thick.
