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]

gollark: Ah yes, because you can totally just modify a language with hundreds of millions of speakers, Solar, totally practical.
gollark: It *looks* kind of simple, but it has an octillion nonsensical weird inconsistencies.
gollark: "not too complex"HAHAHAHAHAHAHAHAHAHA
gollark: We might end up seeing Chinese (don't think Chinese is an actual language - Mandarin or whatever) with English technical terms mixed in.
gollark: Yes, because they have been (are? not sure) lagging behind with modern technological things, and so need(ed?) to use English-programmed English-documented things.
