A mosasaur is a type of dinosaur that lived in the Jurassic period. They can be found throughout the world and on all continents except Australia. Mosasaur fossils are the best-preserved dinosaur bones ever found and they are rare today. Mosasaurus fossils are also notable because they are considerably long-necked dinosaurs as compared to most other dinosaurs.
