Discovery and description

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 2018.[1]
