Cedarosaurus (meaning “Cedar lizard” - named after the Cedar Mountain Formation, in which it was discovered) is a genus of nasal-crested macronarian sauropod dinosaur from the Early Cretaceous Period (Valanginian). The fossils were discovered in 1996 in eastern Utah within the rocks of the Yellow Cat Member of the Cedar Mountain Formation. It was officially named and described by Tidwell, Carpenter and Brooks in 1999. It shows similarities to the brachiosaurid Eucamerotus from the Wessex Formation of southern England, as well as to Brachiosaurus from the Morrison Formation.
