ANN ARBOR, Mich. (AP) — Remains of a mastodon that perished millennia ago are being put back together at the University of Michigan.

The skeleton of the 11,000-year-old female Owosso mastodon was taken apart this spring after standing inside the Ann Arbor school’s natural history museum since 1947. Crews began reassembling her bones this week inside the new Biological Sciences Building next door to the museum.

The ancient, elephant-like mammal eventually will stand beside a cast of the male Buesching mastodon that was found near Fort Wayne, Indiana. Both will be positioned in the five-story atrium of the U-M Museum of Natural History, which opens to the public in April.
