Torosaurus (meaning "perforated lizard", referring to the large openings in the frill; commonly mistranslated as "bull lizard") is a genus of ceratopsid dinosaur that lived during the late Cretaceous period (late Maastrichtian stage), between 66.8 and 65.5 million years ago. It possessed one of the largest skulls of any known land animal. The frilled skull reached 2.6 metres (8.5 ft) in length. From head to tail Torosaurus is thought to have measured about 9 m (30 ft) long and weighed 4 to 6 tonnes (4.4 to 6.6 tons).
