LANE SHALES. 



About seventy-five feet of bluish shales, nearly non-fossil- 

 iferous save in some calcareous layers near their base. The 

 fossils from this horizon were collected in these calcareous 

 layers in the base of the shales at the brick-yards south of 

 lola.

 and Haime).

ALLEN AND STANTON LIMESTONE AND OTHER FORMATIONS. 



At the time of our visit the stratigraphy of the region north 

 of lola was not yet sufficiently well worked out to permit of 

 collecting to the best advantage. All the formations above 

 the lola limestone, or their equivalents, are very much better 

 exposed and vastly more fossiliferous and easily accessible 

 along the Kansas river west from Kansas City. Any one de- 

 siring any adequate knowledge from a limited study of these 

 formations and their faunas should confine their observations 

 to the Kansas river section, if we except region around Cot- 

 tonwood Falls. Under the above heading we include the 

 limestones and shales above the lola and below the Upper 

 Oread at Burlington. The limestone forming an escarpment 

 some few miles south of Burlington was not visited. Collec- 

 tions were made at the Allen limestone on top of the Lane shales 

 at the lola brick-yards, where twenty-eight of the following 

 species were represented. The forms referred to as sponges 

 in the list were confined to this locality. The rocks (three 



persistent limestone above (the Qarnett) it is extremely abundant. However, we have 

 never seen it below that horizon. It should also be stated that Adams, who made the col- 

 lections upon which Qirty based his lists, admitted to the authors in the field that the speci" 

 mensof£'7i<eiete8 from lola were collected from the ballast of the railroad at that place- 

 That ballast was crushed at Garnett, from the Garnett limestone, in which it is very abun- 

 dant. Consequently Girty's statement concerning it in Professional Paper No. 16, U, S. Q. S., 

 p. 2:64, and other places, is in error.
