Tylosaurus pembinensis, a giant sea-dwelling reptile that could open its jaws wide like a snake and swallow large prey. It patrolled the inland sea that divided North America 80 million years ago. A skeleton displayed at the Canadian Fossil Discovery Centre in Modern, Man. is the largest mosasaur skeleton on exhibit in the world. Nicknamed “Bruce,” the centre refers to it as “the T. rex of the sea.”
Chasmosaurus belli, a relative of the famous Triceratops. Its large frill was supported by a bony framework that was likely used for display, not defence. A baby Chasmosaurus was recently found in Dinosaur Provincial Park. It was less than three years old when it died.
Tyrannosaurus rex, the “tyrant king” of dinosaurs. High school teacher Robert Gebhardt discovered one of the largest and most complete skeletons of its kind in Saskatchewan in 1991. The skeleton has been nicknamed “Scotty.”
Ornithomimus edmontonicus, now known to have sported long arm feathers. It used its speed to outrun predators and to hunt for prey, which included small lizards and mammals.
Euoplocephalus tutus, an herb-eater that was known for its spiky, plated armour. Its complex and unusual series of nasal passages may have warmed inhaled air, improved the animal’s sense of smell or helped it vocalize.
