Scientists Found a 42-Foot Sea Monster in the Middle of Canada — It Swam Where Farms Are Now

Ancient Canada reveals an extraordinary discovery from Manitoba: an 80-million-year-old marine reptile nearly 43 feet long, unearthed beneath farmland more than 2,000 kilometres from the nearest ocean. In 1974, workers digging into dark shale near Thornhill, Manitoba, began uncovering enormous fossil bones. Over two field seasons, researchers recovered around 65–70% of a giant mosasaur skeleton measuring 13.05 metres, or 42.8 feet, from nose to tail. The specimen became known as Bruce. Bruce was not a dinosaur. It was a Tylosaurus, a massive marine reptile related to modern monitor lizards and snakes. With powerful jaws, conical teeth and a reinforced snout, animals like this hunted fish, turtles, plesiosaurs and even other mosasaurs in the ancient sea that once covered central North America. That ocean was the Western Interior Seaway, which split North America during the Cretaceous Period. Southern Manitoba was once deep beneath its waters, meaning today’s wheat fields, gravel roads and prairie towns sit on what was once an ancient seafloor. In 2014, Guinness World Records recognized Bruce at 13.05 metres long as the largest mosasaur on public display. The record does not mean it was necessarily the largest mosasaur that ever lived, but it remains one of the most impressive marine reptile skeletons ever put on display. In this video, we explore how a 42-foot sea predator ended up beneath the Canadian prairies, what Bruce actually was, how it hunted, and why the farmland around Morden, Manitoba continues to produce fossils from a vanished ocean. #AncientCanada #CanadaHistory #PrehistoricCanada #Fossils #Paleontology ⚠️ Some visuals are illustrative.
