A farmer found the partial skeleton of a woolly mammoth, which may have lived about 12-13,000 years ago.
Experts from the University of Michigan were able to retrieve about a fifth of the animal's bones during an excavation.
As per reports, there are only 10 similar sites in Michigan where a significant portion of a woolly mammoth skeleton was found. He said this one was likely 40 years old when it probably was killed by humans.
