Trace fossils from two Upper Pennsylvanian sandstones in Kansas

Trails and burrows from two sandstones of the Upper Pennsylvanian of Douglas County, Kansas, are described and interpreted. Some of these are known from the literature, others are new. The trace fossil fauna suggests deposition of the sandstones in littoral shallow water. Although shelly fossils in both units are similar, the differences in the two trace-fossil faunas which have only two species in common indicate presence of two different environments
