remains as occurring in the upper part of the Claggett formation, 

 whereas heretofore it was thought that Coniornis had come from the 

 lower part of the Judith River formation. 



Incidental to this paleontological work a collection of Indian 

 skeletons was obtained for the National Museum. These remains, 

 consisting of parts of eleven individuals, were found in shallow 

 graves in the crevices of a large block of Eagle sandstone that had 

 been faulted up and which forms a conspicuous landmark in the 

 valley just above the mouth of Dog Creek. A picture of this rock 

 is shown in figure IS-

STRATIGRAPHIC STUDIES IN CENTRAL TENNESSEE 



Dr. E. O. Ulrich, associate in paleontology, and R. S. Bassler, 

 U. S. National Museum, were engaged for several weeks during the 

 summer of 1914 in a study of debated points in the stratigraphy 

 of the Central Basin of Tennessee under the joint auspices of the 

 U. S. Geological Survey and the U. S. National Museum. The par- 

 ticular objects of the work were: first, to determine accurately the 

 division line between the Chazyan and Black River groups, and 

 second, to secure additional information on the black shale problem.
