 XIV. NOTES ON THE PALEONTOLOGY OF THE 

 COMANCHEAN OF LOVE COUNTY, 

 OKLAHOMA* 

 Fred M. Bullard 

 Norman, Oklahoma 

 The importance of paleontology in stratigraphic work needs 

 no emphasis. Some of the outstanding facts regarding the paleon- 

 tology of the Com.anchean rocks of Love coimty that the writer has 

 found helpful in his field work will be given in hopes that others 

 working in the area or similar areas wiU find them of assistance. 



It seems desirable before taking up a discussion of the various 



fossil horizons to give a brief summary of the stratigraphy of the 



Comanchean rocks of Love county. The following is the general 



section of the Comanchean of this region. ' 



Group Formation Tickness 



Top in feet. 



Washita Bennington limestone 10 



Bokchito formation 120 



Caddo formation 150 



Kiamichi formation 35 



Fredericksburg Goodland limestone 25 



Trinity Trinity sand 0-600 



The Trinity sand is a loose, unconsolidated pack sand usually 

 white to brown in color. It however contains many lentils of clay 

 and shale and is characteristically extremely variable both in com- 

 position and in thickness. It contains few fossils. Overlying the 

 Trinity sand is the Goodland limestone. It is a hard, massive, white, 

 semicryslalline limestone averaging about 25 feet in thickness. It 

 is very fossiliferous especially in the lower part which contains con- 

 siderable clay. 



Overlying the Goodland limestomc is the Kiamichi formation. 

 It consists chiefly of a marly clay with a hard bed of limestone 

 almost completely filled with oyster shells (Gryphea navia Hall)
