“Big John” is the largest triceratops fossil ever found, with a skull measuring nearly 9 feet long and 6 and a half feet wide. Big John roamed what is now the American West, some 66 million years ago. He was discovered some seven years ago, in 2014. And he’s for sale, via the Druout auction house in Paris, France. The dino is expected to sell for big money. The auctioneers think he’ll go for 1.2 to 1.5 million euro.
