In the sandstone layers interstratified with the shales below the " Putnam Hill Limestone," were found on the land of Mr. Rambo, of which a
section has already been given, fine impressions of Fucoids of the Spirophyton cauda-galli and allied species.
This and similar facts noticed elsewhere, show a wide stratigraphical
range to this group of marine plants. In New York they are found in
the Hamilton rocks. In Ohio they are found in the lower Waverly in
great abundance.
At Gladstone's Mill, near Newtonville, Newton township, Muskingum
county, we find a limestone in the bed of the North Fork of Jonathan's
creek, which is believed to be the same as the Maxville limestone. The
bottom of the stone was not seen, but a well dug in the village passed
through 15 feet of limestone. The upper layer show a chocolate tint. It
is reported that this limestone is seen for five miles in Jonathan's creek,
above Newtonville, and disappears one mile below. On Kent's run, which
joins the North Fork of Jonathan's creek at Newtojville, it is said to be
seen for nine miles.
About 50 feet above the limestone at Gladstone's Mill was found a
stratum of sandstone 15 inches thick, on which are very fine impressions
of marine plants, Spirophyton caudi-galli, &c., &c., and mingled with
these were well-defined stigmariae of the coal-measure plants. They had
all been drifted together and embedded in sand.
The upper limestone (" Putnam Hill") was also seen in its proper place
higher up the hill, with the usual coaly matter under it.
This upper limestone has a pretty extensive range. It was seen in the
Monday creek valley, on the farm of Henry Hazelton, Salt Lick township, Perry county, where was obtained the following section. (See Fig.
12.)
