How many times have you been working on your farm only to uncover the skeleton of a prehistoric mammoth? More than likely your answer is zero. For a farmer near Ann Arbor, Michigan, that answer is “one.”

According to ABC 10 News, the farmer was installing a natural gas line in his wheat field when he made the discovery. University of Michigan researchers were called in to excavate. About 20 percent of the mammoth’s remains were found, as well as what is believed to be a stone tool. The research team believes that the animal was butchered and buried there by humans for future consumption.

Check out the video of the excavation:
