COAL MEASURES FAUNAL STUDIES, II.
(BY J. W. BEEDE AND AUSTIN F. ROGERS.)
FAUNA OF THE SHAWNEE FORMATION (Haworth),
THE WABAUNSEE FORMATION (Prosser),
THE COTTONWOOD LIMESTONE.
BY J. W. BEEDE.
Being a continuation of the foregoing lists of Rogers, published in this journal, vol. IX, No. 4, pp. 232–254.[[1]]
The present paper deals with the fauna of the rocks, beginning at the base of what Haworth has called the “Shawnee formation”[[2]] and continuing upward to the top of the Cottonwood limestone. The strata are treated in ascending order. It must be borne in mind that it is the object of these papers to bring out the fauna of the rocks of the Kansas Coal Measures in sufficient detail to establish time divisions on a paleontological basis. These lists are, of course, incomplete for the horizons in toto, but it is hoped that they do give the characteristic fossils of the rocks of the Kansas river section in sufficient fulness to warrant some deductions of value. The fauna of the Lower Coal Measures still remains to be completed.
20. Kanwaka Shales (Adams MSS., by permission U. S. Geological Survey). Bennett’s description:[[3]] “Above the last (Oread) limestone lies a heavy shale deposit, at least ninety-seven feet thick at Lecompton. The lower sixty-five feet of this is a clay shale, then sixteen feet of arenaceous shale, then five feet of sand rock, above which lies eleven feet of sandy buff shales.” No fossils known from this horizon.
21. Lecompton Limestone. Bennett’s description: “Capping the hills around Lecompton is a five-foot limestone in two layers, which we will provisionally name the ‘Fusulina’ limestone; not that it alone bears that fossil, but because of the abundance of Fusulina in it. It is the lower of another triple system [formation] of limestones, the members of which are separated by a few feet of shale, and which retain this order as far as observed to the west. Above the ‘Fusulina’ stratum are five and one-half feet of clay shales, then one and one-fourth feet of blue limestone, which weathers dark buff, like all its associate strata. Above this are four feet of shales having a bituminous streak in the middle; then ten feet of light gray, easily disintegrated limestone. This group [formation] may be called the Lecompton limestone, on account of their outcropping being near Lecompton. At Spencer, six miles west of Lecompton, the upper part of the series [formation] finally disappears below the alluvial soils of the valley.”
From near the horizon of the above formation, from a well in the road in the bed of Deer creek (the one emptying into Wakarusa creek), near the Shawnee-Douglas county line, the following species have been collected:
