POTTSVILLE FAUNA AND DESCRIPTION 

 OF SPECIES 1 



PLANT KINGDOM 



Plant remains 



Remarks. Plant remains are present in the fossiliferous horizons 

 of the Pottsville formation which are described in this bulletin, although 

 they are by no means common. A considerable variety of forms are 

 represented, but they are, for the most part, too poorly preserved for 

 identification. The scope of the present work does not include a study 

 of the Pottsville flora. 



Horizon and locality. Present at various localities in the Anthony, 

 Boggs, Lower Mercer, and Upper Mercer members, r. 



ANIMAL KINGDOM 



PHYLUM PROTOZOA 



Class Rhizopoda 



ORDER FORAMINIFERA 



Foraminifera of the genus Fusulina occur in the Pottsville rocks 

 of Ohio although they are not present in the extreme abundance which 

 characterizes their presence in the higher formations of the Pennsyl- 

 vanian system of this State. Fusulina secalica (Say) is found in con- 

 siderable numbers in the flinty phases of the Upper Mercer member 

 where it forms the most characteristic fossil of the horizon. It is 

 found as low as the Lower Mercer limestone and extends throughout 

 the middle and upper parts of the formation, although with the excep- 

 tion of the Upper Mercer member, it is of rare occurrence. Other 

 Foraminifera were observed in the Upper Mercer flint, but they are for 

 the most part fragmentary and poorly preserved. Textularia and 

 Nodosaria have been identified with comparative certainty, and judg- 

 ing from the fragmentary material at hand, other forms are in all prob- 

 ability present. 



J In the descriptions of Pottsville species the following symbols are used: aa, very 

 abundant; a, abundant; c, common; r, rare.
