Diver and prehistoric life. Animals shown here include a plesiosaur (upper right), an ichthyosaur (upper left), ammonites (centre right), and a Dapedium fish (orange and blue, lower right). All these animals were present in the Jurassic Period (200 to 145 million years ago), though some were present in earlier and later geologic periods as well. All went extinct long before humans evolved. This artwork could represent time travel, or the recreation of extinct species.
