'''''Morrisonodon brentbaatar''''' is an extinct [[Multituberculata|multituberculate mammal]] from the [[Upper Jurassic]] [[Morrison Formation]] of North America.

''M. brentbaatar'' was described by [[Robert T. Bakker]] in 1998, who originally placed it in the genus ''[[Ctenacodon]]''. The fossil remains consist of a jaw fragment containing two upper [[premolar]]s and the sockets corresponding to two molars. The remains  were found in the Upper Jurassic [[Morrison Formation]] in [[Wyoming]]. The species name honours the Wyoming paleontologist Brent Breithaupt, while "Baatar" is a [[Mongolian language|Mongolian]] for "hero".<ref name=Bakker1998>{{cite book|first=R.T.|last= Bakker|year=1998|chapter=Dinosaur mid-life crisis: the Jurassic-Cretaceous transition in Wyoming and Colorado|title= Lower and Middle Cretaceous terrestrial ecosystems|editor1=S.G.

Bakker assigned his specimens to ''Ctenacodon'' with hesitation, noting additional specimens may require a new classification.<ref name=Bakker1998/> In a 2001 review of multituberculates, [[Zofia Kielan-Jaworowska]] and [[Jørn Hurum]] did not recognize Bakker's specimen as related to other ''Ctenacodon'' species or even belonging to the family [[Allodontidae]], speculating the species might instead belong to the family [[Plagiaulacidae]].<ref name=K-J&H2001>{{cite journal|last1=Kielan-Jaworowska|first1=Zofia|last2=Hurum|first2=Jorn H.|title=Phylogeny and Systematics of Multituberculate Mammals|journal=Palaeontology|date=2001|volume=44|issue=3|pages=389–429|doi=10.1111/1475-4983.00185|s2cid=83592270 |url=http://doc.rero.ch/record/14775/files/PAL_E1903.pdf }}</ref>  In 2004, the species was placed in the newly established genus ''Morrisonodon''.<ref name="Hahn&Hahn2004">{{cite journal|author1=Hahn, G. |author2=Hahn, R. |year=2004|title= The dentition of the Plagiaulacida (Multituberculata, Late Jurassic to Early Cretaceous)|journal= Geologica et Palaeontologica|volume= 38|pages= 119–159}}</ref>
