Summary:

Pg. 31, 170, 179. Amazonia limestone bed of Lawrence shale member of Douglas formation. A limestone, which in places attains thickness of 16 feet in Lawrence shale member of Douglas formation. Lies 25 to 100 feet below top of the Lawrence. Occurs at several places on the point east of town of Amazonia and in the hill west of town; thins to the north and south. At Amazonia (the type locality), consists of gray limestone, nodular at top, weathers buff; thickness 9 feet. Overlying beds are prevailingly arenaceous; underlying beds chiefly argillaceous. Age is Pennsylvanian.
Type locality: measured section at the town of Amazonia, Andrew Co., northwestern MO.
