29. Barclay Limestone. (Adams, MSS., by permission 

 of U. S. Geological Survey.) Base of the Wabaunsee forma- 

 tion. For the present it seems best to group several strata in 

 this formation. 1 ' They cannot well be mapped on the scale of 

 the U. S. folios, and they are also intimately connected faunally, 

 and usually all assist in producing a high escarpment with the 

 upper part retreating. The rocks aggregate about seventy feet 

 in thickness. The following section will serve to give an idea 

 of these rocks : 



ft. in . 

 (/. Gray, argillaceous, fossiliferous limestone, from 1 foot to 2 



/. Bluish calcareous shales with Enteletes, Myalina, Allorisma and 



Bellerophon fauna, from 8 feet to 20 



e. Hard, shelly, bluish limestone 4 



</. Shales with thin limestones, varying from 21 feet to 40 



e. Hard gray limestone weathering light yellow, from 1^ feet to 1 



h. Thin layer of shale 6 



a. Massive yellowish-gray limestone, very hard, with but few fossils, 



from 4 to 7 feet thick, averaging about 6 



Most all of the fossils listed below are from layers e, f, and g, 

 by far the greater part ranging through all three. 



Somphospongia multiformis Beede (from Robinson, Brown 

 county) . 



Aulacorhynchus millepunctatus ( Meek and Worthen ) Hall and 

 Clarke? 



Derby a crassa (Meek and Hayden) Waagen.
