Three boys in southwest Michigan have found a bone from a mammoth.
They really didn't have to dig.
They found the bone on top of soil that had been scraped from a drain.
A professor of paleobiology at Andrews University in Battle Creek, says it's a section of bone from the lower back of a Jefferson's mammoth.
Normally these boys, two brothers and a cousin, who're 7, 9 and 10, look for antique bottles and other things at the edge of their family's property near what used to be a railroad line.
