These four hematite plummets represent three different types. The oldest are the two drilled examples which are Godar plummets that date sometime within the Middle to Late Archaic period. Perino describes them as having their heaviest proportions in the upper half of their length. They range in size from 2 1/2 (6.3cm) to 4 inches (10.2cm) long. The plummet at second from the left is a Gilcrease plummet. Perino describes them as being heavier in the lower half of their length and having grooves very near the upper end. The other plummet is called an Elm point plummet. They are also referred to as "bottle cap" plummets. Perino describes these as being heaviest in the lower half of their length and having an expanded or mushroom-like end. They were first reported from a Late Archaic to Early Woodland burial mound located at Elm Point, Missouri. The burials were covered with red ochre and contained 48 Turkey Tail points, a tube pipe and grooved axes. Perino reports the average length of this type between 2 (5.1cm) and 3 1/2 inches (8.9cm) long.
