Mongolostegus is a genus of stegosaur that lived during the Lower Cretaceous epoch of Mongolia. The fossil evidence is scarce, with only a few vertebrae and some pelvic fossils available. Nevertheless, it is thought that it could grow up to 2.3 meters at the shoulders and reach a length of 7 meters.
The genus of Mongolostegus consists of a single species: M. expextabilis. Alifanov already named the stegosaur in 2005 and 2012. In 2016, Wuerhosaurus mongoliensis, which is now a synonym of M. expectabilis, was found to be invalid and eventually named by Tumanova and Alifanov in 2018.
