Although the mastodon on display at the Geology Museum has long been presented as a complete individual, it was uncovered in 2015 that two bones from the Boaz mastodon were combined with many bones from a different individual, the Anderson Mills mastodon, to form a composite skeleton.


History

Following a heavy rainfall on July 10, 1897, the sons (Harry, Chris, Verne, Clyde) of farmer John Dosch were checking for flood damage along the eastern branch of Mill Creek near the village of Boaz when they discovered some unusual bones sticking out of the creek bank where it had been partially washed away. The boys excavated the bones and displayed them by a hitching post near the road. The local mailman spread the word about the find and the following week stories about it appeared in the ''Republican Observer'', the ''Richland Democrat'', and the ''Viola Observer''. What was described as an arrowhead was found in clay near a rib. The bones were moved to the basement of the Dosch farmhouse. Later, Frank Burnham, a

, attorney and member of the state legislature, negotiated the sale of the bones to the State of Wisconsin for fifty dollars. The skeleton, which is about two-thirds complete and missing its tusks, was reconstructed in 1915 by M. G. Mehl and G. M. Schwartz and is housed in the Geology Museum of the University of Wisconsin. It is estimated that the Boaz mastodon was eighteen feet long, stood nine and a quarter feet high, and weighed six to eight tons.Hopkins, Steve "Ancient Creatures Still Speak" ''Wisconsin State Journal'' June 25, 1989.Palmer, Harris A. and Stoltman, James B."The Boaz Mastodon: A Possible Association of Man and Mastodon in Wisconsin" ''Mid-Continental Journal of Archaeology'' Vol.1 No.2, 1976.Pease, Harry S. "In Search of the Ancients" ''The Milwaukee Journal'' July 30, 1978. The arrowhead did not accompany the bones when they were sent to the University of Wisconsin. In the 1940s the University received an envelope containing a quartzite spear point. The return address on the envelope was D. C. L. Dosch, Maysville, Missouri, and scribbled on the envelope was "allegidly found with U.W. elephant". In 1962, the two surviving Dosch brothers identified the point as like the one they had found 66 years previously. The fluted spear point is made of quartzite from the
