Mastodon animal age2/27/2024 This is Fred’s story, as best as Fisher and his colleagues can tell.īy all indications, Fred was a happy young mastodon, his welfare secured by a doting mother and the watchful aegis of his aunts. He migrated across the Midwest with the seasons, living in a world about to change forever. But inscribed in Fred’s own bowed tusks scientists have found a “ticker-tape record of his entire life.” Written in bone are 13,200-year-old memories of a mastodon living in the twilight days of his species. That is, the mastodon was probably killed by another one. “It got a tusk tip into the cheek,” says the University of Michigan paleontologist Daniel Fisher, grimly signaling to the roof of his mouth. That this animal, nicknamed Fred, might have had his own biography is betrayed only by the ominous hole on the underside of his skull. Such relics rarely get to speak of their own lives. The mastodon pulled from the Indiana muck now lives in the state museum, looming over visitors, a stand-in for his entire species and epoch. Yet we know little of the lives of these animals with which we shared the planet for hundreds of thousands of years. The last mammoth, for instance, died after the first pyramids were built. Although they might be popularly imagined living way back with the dinosaurs, the Ice Age megafauna went extinct only moments ago, in staggered waves over human history. Bone is the right word: This bone belonged to a mastodon, and mastodons are still fresh bodies in the dirt, not petrified fossils entombed in the rock. In 1998, outside of Fort Wayne, Indiana, a hydraulic excavator at Buesching’s Peat Moss & Mulch stripped back a layer of peat and struck bone in the underlying marl.
