Book excerpt: Excerpt from Conodonts From the Glen Dean Formation (Chester) Of the Illinois Basin Studies of conodonts from 'the Chester Series in the type area of southwestern Illi nois (rexroad, 1957) showed a diversified fauna from eight formations and indicated that conodonts will be useful in strati graphic investigations of Chester strata. Although the earlier study established-the Chester conodont fauna as a whole, that study was confined to one area and mainly to the shale beds. Thus it did not allow evaluation of limestone faunas, effects of facies changes, nor faunal variations Within; a single formation over a broad area. Such details, along with the more precise delim iting of stratigraphic ranges within the se ries, were the objectives of the present study. The Glen Dean Formation was chosen for study because: (1) it contains relatively abundant conodonts in the type area of the Chester Series; (2) it is well exposed around the margin of the Illinois Basin; (3) in much of its outcrop area it consists of a lower massive limestone unit and an upper unit of mixed lithology, dominantly shale, which would be desirable for facies analysis.
