In Walking with Giants, we follow 167-million-year-old dinosaur tracks in the ancient ocean shores of…Wyoming?

For part of the Middle Jurassic, Wyoming was covered periodically by an ancient ocean called the Sundance Sea. Until the tracks were found, scientists thought that only sea-dwelling creatures could have lived in the area which would mean there shouldn’t be any dinosaur footprints here at all. But there are thousands of tracks in the 40-acre area.
