In 1978, Gary Johnson found a super heavy rock sitting in his backyard, so he dug it out and took it to an expert. This ‘expert’ said it was just a plain rock and had no value. Flash-forward to 2014, when Gary saw a report on the news about a recently discovered whale skull, that was unearthed nearby to where he found his rock. This time, he called a palaeontologist, who confirmed that he had a fossil from a rare baleen whale, that roamed the earth 14 million years ago.
