HUBBARD AND CRONEIS 
replaced by green, sandy shale, to rocks which in turn merge 
into thin bedded green sandstones. Only the dark division is 
called Romney, the upper portions being designated as Kim- 
berling. 
The true Romney shale at the type locality, Romney, W. Vir- 
ginia, is reported to contain fossils of Onondaga, Marcellus, and 
Hamilton age. The Romney of Giles County is thought by Stose 
and Miser to be of Genessee and lower Portage time and there- 
fore younger.^® At the base of the Romney, however, near Big 
Stone Gap there have been found fossils of Hamilton and Mar- 
cellus age in a thin layer of disturbed, rusty, black shale. True 
Romney has been deposited, it would seem, but has almost en- 
tirely been removed by erosion. The thickness of the so-called 
Romney is about 500 feet. 
Again, exposures in Clendenning Creek are clearly of Marcellus 
age for they contain the following forms : Camanotoechia cf . 
exemia, Stropholosia truncata, Leiorhynchus Umitare, Styliolina 
fissurella, Tentaculites bellulus, and Ambocoelia umbonata. 
These include forms said by Kindle^®^- to be characteristic of the 
Marcellus. To continue, none of the forms said by H. S. Williams 
to be characteristic of the Genesee have been found in the Nar- 
rows section. Hence, the evidence from both sides seems to 
point to Marcellus age for the Romney of Giles County. 
The Kimberling Shale 
As has been mentioned before, this formation passes from 
greenish or gray fissile shale to sandstone and appears to be 
about 3000 feet in thickness. Fossils, which are not numerous in 
this form.ation, indicate Portage and Chemung age. The sand- 
stone at the top may in part be Catskill although no flora or 
fauna were found in this horizon. 
None of the Devonian of Giles County presented outcrops 
which could be subdivided easily since by far the greatest portion 
of these rocks is shale which weathers very rapidly.
