TRADEWATER GROUP 



65 



signed to the position of the Battery Rock 

 coal bed, but more recently (Moore, Wan- 

 less, Weller, et al., 1944) to the position of 

 the Reynoldsburg coal bed. The plant 

 spores of these two coal beds lack similarity, 

 indicating that the beds are not equivalent. 

 In all probability the sequence in a com- 

 plete section including both western and 

 southern Illinois would be as follows : 

 Tradewater Group 



Babylon coal bed 



"Sub-Babylon" coal bed 

 Caseyville Group 



Reynoldsburg coal bed 



Battery Rock coal bed 



Wayside coal bed 



Therefore, the oldest Pennsylvanian 

 strata in southern Illinois are of Caseyville 

 age, and in western Illinois are of Trade- 

 water age.

 fied from macerations 523 and 588, Fulton

Willis and Tarter Coal Beds 

 The Willis coal bed from Gallatin Coun- 

 ty (Schneider's Mine— NW. V A SE. \/ A sec. 

 30, T. 10 S., R. 9 E.) is correlated by plant 

 spores with the Tarter coal bed in Fulton 

 County (NW. \/ A NW. \/ A SE. \/ A sec. 19, 

 T. 5 N., R. 2 E.). This correlation is in 

 agreement with that made by Wanless 

 (1939), Henbest and Dunbar (1944), 

 Moore, Wanless, Weller et al. (1944) and 

 Cooper (1946). 



The following list of genera and species 

 have been isolated and identified from both 

 beds with two exceptions which are indi- 

 cated in the list :

* Refers to a type of spore which is to be described in 

 a later publication by another author. 



The occurrence of a single form of Alati- 

 sporites trialatus sp. nov. in the Tarter bed 

 and a fragment of Reinschospora sp. in the 

 Willis bed is considered a minor discrep- 

 ancy, in view of the similarity in relative 

 abundance of the more numerous forms. 

 The dominant spore genus is Laevigato- 

 sporites which comprises 39 percent of the 

 spore content of the Tarter bed and 35 

 percent of the spore content of the Willis 

 bed. The subdominant genus is Cirratrira- 

 dites which comprises 26 percent of the 

 spore content of the Tarter bed and 27 

 percent of the spore content of the Willis 

 bed. The remaining genera are equally 

 abundant in the two areas investigated. 



* One specimen observed in the Tarter coal bed out of 

 over 5000 examined. 



** One fragment of a specimen of this genus observed 

 from the Willis coal bed.
