Mongolostegus Explained
Mongolostegus (meaning "Mongolian roof") is a genus of stegosaur from the Early Cretaceous (Aptian-Albian) Dzunbain Formation of Mongolia. The type and only species is M. exspectabilis,[1] known from a single specimen previously under the nomen nudum Wuerhosaurus mongoliensis.
Mongolostegus is one of the youngest known stegosaurs, along with Stegosaurus,[2] Yanbeilong,[3] and an unnamed species from the Dzunbain Formation.
Discovery and description
The holotype is PIN 3779-15, which consists of posterior dorsal and anterior caudal vertebrae as well as pelvic material. It was discovered in a layer of the Dzunbain Formation at Chamrin-Us, Mongolia.
Mongolostegus was first reported by Alifanov et al. (2005) and Alifanov (2012) as an indeterminate stegosaur.[4] [5]
Ulansky (2014) informally dubbed the material Wuerhosaurus mongoliensis,[6] but Galton and Carpenter (2016) found W. mongoliensis to be invalid.[7] It was formally named as Mongolostegus by Tumanova and Alifanov in 2018.
Classification
Tumanova and Alifanov (2018) found Mongolostegus to belong to Stegosauridae.
