Claosaurus (/ˌkleɪəˈsɔːrəs/ KLAY-ə-SAWR-əs; Greek κλάω, klao meaning 'broken' and σαῦρος, sauros meaning 'lizard'; "broken lizard", referring to the odd position of the fossils when discovered) is a genus of primitive hadrosaurian (early duck-billed dinosaur) that lived during the Late Cretaceous Period (Campanian).
Traditionally classified as an early member of the family Hadrosauridae, a 2008 analysis found Claosaurus agilis to be outside of the clade containing Hadrosaurus and other hadrosaurids, making it the closest non-hadrosaurid relative of true hadrosaurids within the clade Hadrosauria.[2]
