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]

  • J. aralensis Riabinin, 1937 (type)

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, cropping low-lying plants with their toothless beaks and chewed them with their cheek teeth.

Taxonomy

The type species, J. aralensis, was first described by Anatoly Nikolaevich 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]

gollark: Fixed types, fixed length.
gollark: No, they would be `(a, b)`.
gollark: What? No. This is another weird-special-casing thing.
gollark: Oh, and another thing! The multiple return values syntax there can't be used for tuples or something.
gollark: Someone might use that value by mistake.
