Grammysia sp (rr)

Further up the creek were loose shales in which additional species 
of fossils were found; also some shales of somewhat different lithologic 
character containing fragments of fossil plants, which closely resemble

The specimens are fragmentary in an arenaceous shale and possibly are 
only fern stipes. It is very difficult to identify such fragmentary remains 
of fossil plants, and on that account their evidence is of very little value. 
The custom of the older paleobotanists seems to have been very gener- 
ally to describe such remains, when from different localities or forma- 
tions, as new species. In this way the list of so-called species of fossil 
plants has attained great dimensions, the number of which is being most 
industriously increased by some students of paleobotany. 
No. 1476 A7. — By the roadside above the Yedder schoolhouse, rather 
coarse arenaceous shales which correspond to the typical, moderately 
coarse, arenaceous Hamilton shales of Hamilton, N. Y., and contain 
plenty of fossils. 
Fauna No. 1476 A7 (Along the Highway above Marshalls Falls). 
Palseoneilo constricta (Con.) Hall (r) 
Another specimen, which is broken, is quite elongate and resembles some- 
what P. plana Hall.
