Abstract

A Des Moines sandstone cave deposit in Lower Davenport limestone was, until recently, exposed in a quarry one-half mile northeast of Robins, Linn County, Iowa. The quarry is in the Northeast Quarter of Section 22, Township 48 North, Range 7 West. The rock containing the plant fossils is a medium to fine grained, buff sandstone that was about 32 feet wide with a maximum thickness of 18 inches when examined in January, 1938. Since then, recent quarrying operations have completely removed the deposit. Plant material was abundant through the deposit but very fragmental. The larger fragments are highly ferruginated or pyritized and the remainder are either impressions or carbonized leaves.
