50 Fossil Corals of Franklin Counly, Indiana. 



FOSSIL COEALS OF FEANKLIN COUNTY, INDIANA. 



Bv David R. Moore. 



The distribution of Fossil Corals in Franklin County is confined to 

 the Lower and Upper Silurian ages, and Devonian drift. 



For variety in genera and species the large area of the Lower Silurian 

 presents an interesting field. 



A few Upper Silurian representatives are found in the localities of 

 outcrops of that age. 



Representatives from the Devonian drift form no inconsiderable 

 part of the Palaeontology of the County. 



The following list is far from exhaustive ; but indicative of the extent 

 and variety of ancient Coral life within the bounds of the County ; also 

 of progress so far made in the discovery and determination of genera 

 and species. 



As Curator of Geology, and especially in the work of preparing this 

 list, I am indebted to other members of the Society for valuable aid. 



The authorities exclusively depended upon for descriptions and 

 nomenclature are the Palaeontology of Ohio, Vol. II ; and the Indiana 

 Geological Reports of 1881-82.
