Ptilodontidae is a family of fossil mammals within the extinct order Multituberculata. Representatives are known from the Upper Cretaceous and Paleocene of North America.
For the technically minded, this family is part of the suborder of Cimolodonta, within the superfamily of Ptilodontoidea.
Taxon: Ptilodontidae (Cope ED, 1887) Gregory & Simpson, 1926
Remarks: This grouping has also been seen as a subfamily; Ptilodontinae (Cope, 1887). Chirogidae Cope ED, 1887 is a synonym. Despite Cope's original title, Chirox, a synonym of Ptilodus, was no more a marsupial than I am. It was much more distantly related.
