Mongolostegus is a genus of stegosaur from the Early Cretaceous (Aptian-Albian) of Mongolia. The type and only species is M. exspectabilis, known from a single specimen previously under the nomen nudum Wuerhosaurus mongoliensis.[1] It is the youngest known stegosaur (excluding Dravidosaurus, which may have been a plesiosaur and not a stegosaur), living around 100 million years old.
History of study[]
Mongolostegus was first reported by Alifanov et al. (2005) and Alifanov (2012) as an indeterminate stegosaur based on posterior dorsal and anterior caudal vertebrae as well as pelvic material.[2][3] Ulansky (2014) informally dubbed the material Wuerhosaurus mongoliensis, but Galton and Carpenter (2016) found W. mongoliensis to be invalid.[4] It was formally named as Mongolostegus by Tumanova and Alifanov in 2019.[1]
