Description

Mammut Americanum , more commonly known as the American Mastodon, is an extinct species found throughout North and Central America. Dated from either the Aftonian or Yarmouth age (120,000 to 200,000 B.C.E.), a 12 foot, 600 pound tusk of a mastodon was discovered in Hampton, Iowa in the 1930’s.

In 1933, it was brought to the University of Northern Iowa for comprehensive research and preservation. The tusk was covered in unknown materials such as varnish, spackle, lacquer, and shellac in an attempt to preserve it before putting it on display in the UNI Museum in the 1960’s. Currently, the tusk is in two pieces, the smaller of which was the subject of this research.

Fluorescence mapping of the materials on the Mastodon tusk is a necessary study as the lacquers hold the key to determining the future preservation methods required by the tusk.
