Discovery: Found by Dr. Hans Larsson and his paleontology field team in Eastend, southern Saskatchewan (collected under permit from the Royal Saskatchewan Museum).
Lived during: Late Cretaceous
Diet: Herbivore. Ate plants, possibly small trees.
Habitat: Discovered in Alberta to Colorado, and Saskatchewan to South Dakota.
Behaviour: Lived in packs of hundreds or thousands.
Other info: Aside from defense, horns may have been used for attracting a mate as they changed shape and orientation between childhood and adulthood. The stiff frill at the back of the triceratops’ head also changed shape and orientation so it may have also been used to attract a mate. Jaws were tipped with a beak which allowed them to pluck the low plants they ate. It is believed they may have eaten small trees because their jaw muscles were so powerful.
