Torosaurus was a large ceratopsid dinosaur. Its name means "perforated lizard", although often incorrectly interpreted as "bull lizard". It very much resembled its cousin Triceratops, but had a much longer frill, with two large holes (or fenestrae). In 2009 researchers under supervision of Jack Horner argued that Torosaurus was the oldest form of Triceratops. The massive frill of Triceratops would grow longer and thinner in time, until it may have had the same holes as seen in Torosaurus. However, this has since been disproven, as young Torosaurus fossils have been found. Torosaurus may have lived in herds, like many of its relatives, but experts are not sure, since no fossils have been found in large numbers. It was long thought to have the largest skull of any animal in history, but it seems in recent years that Pentaceratops has topped its record.
