Remains of a woolly mammoth discovered on a Michigan field by farmers who were working to drain water from the land. 

The head, tusks, ribs and set of vertebrae from a woolly mammoth have been discovered on a farm in Lima Township, in Michigan.

Remarkably, they were unearthed by accident by farmers Trent Satterthwaite and James Bristle, who were working to drain water from part of Mr Bristle's farm.

The pair dug for about eight feet until they found a wood-like substance.

On further inspection, they soon discovered it was actually bone and contacted the University of Michigan.
