Purpose of Investigation

This report is a description of ten cores collected in the Hamilton area of Greenwood County, Kansas by the Kansas Geological Survey during the Summer of 1988. The purpose of collecting and describing the core was to provide additional data for an ongoing study (being conducted by the Kansas Geological Survey and other organizations) concerning the stratigraphy and depositional setting of the Hamilton Lagerstätte and associated units. The Hamilton Lagerstätte is an interval of dolomitic mudstones and shale which yields a well preserved fossil biota of primarily terrestrial plants, vertebrates, and invertebrates, and minor numbers of marine fossils (See Mapes and Mapes, eds., 1988). Fossil have been collected and described from this interval for nearly twenty years (Bridge and Mapes, 1988), but only recently has attention been paid to possible stratigraphic relationships and depositional setting of this unit.
