Fauna of the Brazil Limestone. 



By F. C. Greene. 



Prof. Chas. W. Shannon of Brazil sent to the State University a col- 

 lection of fossils which he said came from a limestone just below the sur- 

 face at that place. Later Dr. J. W. Beede of the State University and 

 Mr. L. C. Snider sent in other collections from the same limestone at 

 somewhat different localities in the same vicinity. 



The stratigraphic chart in the 33rd annual report of this department 

 shows this limestone as occurring in Division II of the Indiana Coal Meas- 

 ures. In the 23rd annual report of this department, Ashley gives the fol- 

 lowing sections from this locality :

In other places in this vicinity, the limestone is only seven feet thick 

 or may be wanting, while the underlying shale varies from to S feet in 

 thickness. The limestone is a dark-colored, bituminous stone, having an 

 irregular fracture and the fossils are mainly white or light-colored. It is 

 sometimes overlain by -^ery fossiliferous, dark-colored, calcareous shale 

 from which flnelj^ preserved specimens maj' be washed.
