Samples taken from the tusk of the Buesching mastodon in Indianna may shed light on how prehistoric animals migrated.
And thanks to modern technology, scientists can now understand more about this prehistoric mammal. Researchers from the University of Cincinnati, the University of Michigan and the University of Nebraska-Lincoln used a geochemical process to determine the migration patterns ofmastodon was first discovered near Fort Wayne, Ind. in 1998. Experts believe a rival mastodon tusk punctured the right side of his skull and killed the mastodon.
"Using new modeling techniques and a powerful geochemical toolkit, we've been able to show that large male mastodons, like Buesching, migrated every year to the mating grounds," says Miller in a press release. Operating under a microscope, researchers drilled half a millimeter into the 13,000-year-old tusk, and collected powdered residue to chemically analyze.
After chemically analyzing the residue, researchers were able to find that the strontium isotopes levels, found in certain areas, in the tusk acted like a map to pinpoint where the mastodon had been during his life. The oxygen isotopes also found in the tusk were able to determine what time of year the mastodon spent at a certain location.
