Jaxartosaurus Characteristics

Jaxartosaurus measured around 30 feet (9 metres) in length and 16 feet (4.9 metres) in height. Its weight is unknown. Jaxartosaurus had a large, helmet-like crest that it used to vocalize with members of the same herd. Females had the smallest crests and juveniles had none at all. This wide-headed plant-eater had flat-topped cheek teeth. Jaxartosaurus was a bipedal dinosaur and walked around on its 2 strong hind legs. Its forelimbs were short and it had a long, heavy, stiff tail which was probably used to counter-balance. This dinosaurs skull had a joint similiar to one found on modern crocodiles, a joint which may have acted as a shock absorber during sudden closing of its jaws.


Jaxartosaurus was a herbivorous dinosaur who probably ate huge amounts of plant material to sustains itself.


Jaxartosaurus fossils were found in China. Fragmentary fossils (just the skull roof and braincase) were found near the Jaxartes River in the Aral Mountains, Kazakhstan, Asia.


Jaxartosaurus was named by Riabinin in 1934.
