Mongolostegus
Sign in to saveMongolostegus (meaning "Mongolian roof") is an extinct genus of stegosaurian dinosaurs from the Early Cretaceous (Aptian–Albian ages) Dzunbain Formation of Mongolia. The genus contains a single species, Mongolostegus exspectabilis, known from a fragmentary single specimen representing the first stegosaur named from Mongolia. It is one of the youngest known stegosaurs, along with Yanbeilong and an unnamed species from the Hekou Group of China. In contrast to these taxa, which are members of the late-diverging stegosaur subfamily Stegosaurinae, Mongolostegus may have affinities to more basal tax

Mongolostegus (meaning "Mongolian roof") is an extinct genus of stegosaurian dinosaurs from the Early Cretaceous (Aptian–Albian ages) Dzunbain Formation of Mongolia. The genus contains a single species, Mongolostegus exspectabilis, known from a fragmentary single specimen representing the first stegosaur named from Mongolia. It is one of the youngest known stegosaurs, along with Yanbeilong and an unnamed species from the Hekou Group of China. In contrast to these taxa, which are members of the late-diverging stegosaur subfamily Stegosaurinae, Mongolostegus may have affinities to more basal taxa such as the Huayangosauridae.
