FOSSILIFEROUS HORIZONS AND FOSSIL FLORA. 313 



and below the vSewell coal fossils were found at Turkey Knob and Hawks 

 Nest. From the Sewell coal ])lants were collected at Stone ClitT, Turkey 

 Knob, MacDonald, Thurmond, Brooklyn, C'unard, Nuttall and Hawks 

 Nest (see /, figure 2). Plants were found at several horizons between the 

 Sewell or Nuttall coal and the base of the '' Honiewood sandstone " at 

 Nuttall and Hawks Nest (see J and K, fi«2;ure 2). At the last named 

 locality a little material was dug from a parting in the Homewood itself 

 (see L, figure 2). These were the liighest plants collected from the Potts- 

 vilie series. Some material was obtained from a coal in the Lower Pro- 

 ductive Coal Measures, or ''Alleghany series " of I. C. White, a short 

 distance above the Homewood sandstone. 



FOSSIL PLAXTS XEAR THE LOWER COXGLOMERATE OX PIXEY CREEK. 



As it is not my purpose in this paper to attempt any local or detailed 

 paleontologic correlations, I shall consider only the plants obtained from 

 a few of the richer or more interesting horizons. 



The identifications are preliminary, and many of the names, for reasons 

 stated at the beginning, are, pending revision or description, merely tenta- 

 tive and subject to change. 



The shales immediately above and below the lower Piney Creek con- 

 glomerate, which, like portions of the conglomerate itself, are more or 

 less calcareous, are j)oor in plants. From those at the base (see ^4, figure 

 1) I obtained : 



Sphenopteris subgetiiciikita, (Stur. ) Schiitze (?). 

 Spheywpteris cf. decomposiia, Kidst. 

 Asterophyllites, sp. indet. 



Sphenopteris suhfjenknJata is one of the European Culm species, while 

 S, decomposita is found in the Calciferous Sandstone series of Scotland. 



From immediately above this conglomerate (see B, figure 1) were 

 obtained : 



Adiantites, sp. smaller than antlfjnus, (Ett.) Stur. 



Sphenopteris, sp. extremely lux. 



Sphenopteris dlstans, Stb. 



Asterophi/llitts ef. niiniitn,^, Aiidr. 



Carpolith's, small. 



Rhahdocarpus, n. sp. 



Here again those acquainted with Paleozoic fossil plants will recognize 

 a general Lower Carboniferous cast, though the forms are few. Sphenop- 

 teris didans is a true Culm species, being one of the characteristic })lants 

 of the Hainichen-Ebersdorf Culm and the roofing-slates of Monivian 

 Silesia. 



About 150 feet of largely calcareous red and green shale and sand-
