This hemisphere was found several years ago by Delmont Person, probably in Madison County, Illinois. It's the smallest example in the group that is illustrated in this report. There was no attempt to polish any of the surfaces. The pecking marks are still very evident. It appears that this example may not have been completed. Each side still has some remnant of the original outer cortex of the pebble it was made from. This example clearly shows that some of these hemispheres were probably made from small pebbles that didn't need to much work to finished them out. This hemisphere measures 1 9/16 inches (4 cm) long, 1 5/16 inches (3.3 cm) high and 1 3/16 inches (3 cm) thick.
