80 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 127 
Neuman named the 800-foot sequence of “Stones River” the Row Park 
formation. Cooper and Cooper had previously identified this sequence as Whistle 
Creek on the basis of contained fossils. Below the New Market of Cooper 
and Cooper, Neuman discovered granular limestone containing abundance of 
Rostricellula. 
The seemingly conflicting identifications of New Market by Cooper and 
Cooper and Neuman can be interpreted as a facies condition. 
It is postulated here that both identifications of New Market are correct, but 
that the Row Park is a partial facies of the New Market and also the Whistle 
Creek. Neuman shows New Market lithology interfingering with Maclurites- 
bearing limestones. The same situation can be seen at Wilson, Md., and in the 
big quarry at Pinesburg, Md. Thus the New Market is sandwiched between 
Rostricellula beds of the Row Park at the base and the main body of the Row 
Park. It interfingers with the main mass of the Row Park. New Market also 
overlies Row Park, as it does near Marion. 
A more moot point is the suggestion by B. N. Cooper and G. A. Cooper 
(1946, p. 70) that New Market (their “Lowville” facies) interfingers also with 
the Lincolnshire which overlies New Market at its type section. The Lincoln- 
shire thins to the northeast in the same direction in which the New Market 
thickens. Lincolnshire is not certainly known in Maryland, but a tongue of dark 
limestone on the New Market in a quarry at Wilson is tentatively indentified 
as Lincolnshire. 
The facies shifts described above are like those that occur elsewhere in the 
Appalachians. In fact the whole of the Appalachian sequence treated herein, 
except the Martinsburg, passes into calcilutites of one kind or another. 
Few brachiopods have been taken from the New Market: 
Pionomena neumant Cooper 
Rostricellula elliptica Cooper 
Oak Hall member of Nealmont formation.—This member was defined by 
Kay (1944, p. 97) for exposures on Pennsylvania Highway 322, 1 mile west of 
Tusseyville, Pa. The Oak Hall is the lowest member of the Nealmont formation 
and consists of heavy-bedded limestone about 60 feet thick. The Oak Hall lies 
unconformably over the Valentine formation. At Bellefonte, Pa., the Oak Hall is 
absent from the Nealmont formation, except for channels in the underlying 
limestone. 
Ancistrorhyncha sp. = A. australis (Foerste) 
Camarotoechia sp. = Rostricellula sp. 
Leptaena (?) sp. cf. L. charlottae Winchell and Schuchert = Bellimurina 
Leptaena sp. 
Zygospira recurvirostris (Hall) 
Ooltewah formation (B. N. Cooper and G. A. Cooper).—This formation, 
named from Ooltewah, Hamilton County, Tenn., consists of 250 to 600 feet of 
ribbon-banded Camarocladia-bearing limestone with numerous intercalations of 
red Moccasin-type mudstone and fewer interbeds of buff shaly limestone over-
