<i>Centrosaurus</i> (SEN-tro-sawr-us) meaning "pointed lizard" (from Greek kentron/κεντρον = "point or prickle" + sauros/σαυρος = "lizard"), in reference to the hornlets on its frill, but not as is often stated to the (at the moment of naming unknown) horn on its nose, was a herbivorous ceratopsid dinosaur from the late Cretaceous period of North America about 75 million years ago. The first discovery of this species was in Alberta, Canada.
