Chasmosaurus

   

Chasmosaurus was a ceratopsid dinosaur that lived in the Late Cretaceous period and greatly resembled a Triceratops. Its name means "open lizard" due to the large holes in its frill, and it was purely herbivorous. Chasmosaurus is found in almost all of western North America, which was still Laramidia in the time of Chasmosaurus, around 75 million years ago. It gives its name to the Chasmosaurinae, which is one of two main types of Ceratopsian, the other being the Centrosaurinae. The latter is known for its shorter frills and generally more elaborate and numerous horns. The Chasmosaurinae evolved later, though the Ceratopsians as a whole were relative latecomers compared to other Dinosaurs. The Chasmosaurinae are characterised by their more extensive frills and longer horns. Strangely enough, Chasmosaurus itself is an early example of the Chasmosaurinae, and lived alongside many Centosaurine Ceratopsians, such as Centrosaurus, Styracosaurus and Pachyrhinosaurus. It had one of the largest skulls of any land animal, with only Pentaceratops, Triceratops and Torosaurus exceeding it in length (Pterosaurs, Hatzegopteryx and Quetzalcoatlus, technically also with their massive skulls). from the Jurassic Park wiki
