REPORT OF STATE GEOLOGIST. 



ferson County southward. If we may judge from the rich fauna 

 which characterizes the Waldron shale in western Tennessee," the 

 sparse fauna of the shale in the southern part of Indiana is not 

 connected with any conditions unfavorable to life which were as- 

 sociated with the southern part of the Waldron shale basin of depo- 

 sition. It seems probable that the Waldron shale a few miles to 

 the west of its outcrops in Clark and southern Jefferson counties 

 contains a fauna similar in richness to the Waldron localities. The 

 distribution of the Waldron fauna, as we know it from the out- 

 crops of the Waldron formation, is shown in the following list. 

 The names of the several localities are arranged from left to right 

 in the same order as their relative geographic position from north 

 to south. Hartsville lies 12, Vernon 30, Dupont 38, Paris Cross- 

 ing 42, and Hanover 50 miles south or southeast of Waldron.

I' This list includes all of the species recorded by Hall from Waldron and by Cumniings from Hartsville. 

 The 12 species added to Cummings' list of the fauna at Tarr Hole are mainly from two localities near Hartsville 

 not represented in the Cummings collection, viz.: Clifty Falls and a ravine southwest of Hartsville, J of a mile. 



cThe fossils from Dupont are given on the authority of Foerste, 21st. Ann. Rept. Ind. Geol. Surv. p. 257. 



<1 A very small collection was made at Paris and the few species here listed from this locality are not repre- 

 sentative of the richness of the fauna.
