Haworth—Stratigraphy of the Kansas Coal Measures. 457 
stone is the “cement rock” quarried and manufactured so 
extensively into hydraulic cement at Fort Scott. 
Both of the limestones and the associated black shales are 
well filled with fossils, from the list of which the following are 
representatives. The corals and crinoids are particularly 
abundant and large. usulina ventricosa (?) ; Campophyl- 
lum torquium , Syringopora multatenuata ; Zeacrinus mucro- 
spinus ; Chaetetes milleporaceus, very plentiful ; Ptilodictia 
triangulata, rare; Lhombopora lepidodendroides ; Chonetes 
mesoloba ; Productus costatus ; Productus nebrascensis ; Pro- 
ductus punctatus; Letzia mormoni; Lhynchonella uta; 
Spirifera lineata; Allorisma subcuniata; Aviculopecten 
, first seen in upper limestone; Wuculana bellistriata ; 
Orthis carbonaria,; Bellerophon montfortanus ; Naticopsis 
ventricosa , Pleurotomaria sphaerulata ; Gonetites i 
Nautilus ferratus ; Orthoceras rushensis ; Phillipsia major. 
The Pawnee Limestone.*—In the southern part of the state 
a shale bed which in places reaches a thickness of 60 feet and 
which carries considerable coal, lies immediately above the 
Oswego limestone, but it seems to thin out towards the north. 
Above this a limestone occurs which likewise thins towards 
the north, but which is very prominent on the uplands around 
Fort Scott and to the southwest. At one place to the west of 
Fort Scott it reaches a thickness of 35 feet. It extends west- 
ward to beyond Cherryvale and northward to the vicinity of 
Pleasanton, beyond which it seems to disappear. It affords the 
following fossils in considerable abundance, with many others 
not given: Cyathaxonia distorta; Lophophyllum proli- 
ferum; Fistulapora nodulifera; Productus longispinus ; 
Spirifera lineata; Spiriferina kentuckiensis ; Plewroto- 
maria sphaerulata. 
The Pleasanton Shales.t~—Above the Pawnee limestone 
lies a shale bed of considerable importance. In the vicinity 
of Pleasanton and Boicourt it is fully 200 feet thick. To the 
south it maintains its thickness tolerably well to beyond the south 
line of Kansas, but perhaps not in quite as heavy beds as 
around Pleasanton. Northward it decreases slightly, but 
regains this thickness at Paola and is 180 feet thick at Kansas 
City. Westward it seems to maintain its thickness quite well. 
At Iola, according to the record of the Iola well, it is over 250 
feet thick. 
In places the Pleasanton shales carry much sandstone, a 
noted instance of which is within ten feet of a summit at Bot- 
court. Here extensive quarry operations were once con- 
ducted. They carry two coal veins equalling from twenty-
