Jaxartosaurus (meaning "Jaxartes lizard" after the early name of the Syr Darya) is a genus of hadrosaurid dinosaur similar to Corythosaurus which lived during the Late Cretaceous. Its fossils were found in Kazakhstan.[1]

Discovery

The type species, J. aralensis, was first described by Anatoly Riabinin in 1937.[1] A second species, J. fuyunensis, was described by Wu (1984) for a dentary from Xinjiang, China, but is dubious.[2][3]

Description

Jaxartosaurus had a large crest that it may have used for visual identification, or to vocalize with members of the same species, as inferred for other lambeosaurines. They were likely herbivores, grazing on low-lying plants.
