Tooth of a tyrannosaurid theropod dinosaur — possibly Albertosaurus — cast (from Mid-Land Scientific Service of Canada) of an original specimen collected from the Upper Cretaceous Judith River Formation of Red Deer River Valley, Alberta.
Below, souvenir postcards from the Tyrrell Museum of Palaeontology, Drumheller, Canada, showing a life-sized statue of Albertosaurus (“Lillian,” the museum’s mascot); reproducing a painting by Gregory S. Paul of a herd of the horned dinosaur Styracosaurus fleeing the closely related Canadian tyrannosaurid Gorgosaurus; and, from the Denver Museum of Nature and Science, reproducing a painting by John Gurche depicting the related Canadian tyrannosaurid Daspletosaurus vs. Styracosaurus.
