(Credit:Photo credit: Eric Bronson, Michigan Photography.) A mounted skeleton of the Buesching mastodon, based on casts of individual bones produced in fiberglass, on public display at the University of Michigan Museum of Natural History in Ann Arbor. The Buesching mastodon is a nearly complete skeleton of an adult male recovered in 1998 from a peat farm near Fort Wayne, Indiana. A new study, led by Joshua Miller of the University of Cincinnati and Daniel Fisher of the University of Michigan, uses oxygen and strontium isotopes from the mastodon's right tusk to reconstruct changing patterns of landscape use during its lifetime.
