Ptilodontidae is a family of fossil mammals within the extinct order Multituberculata. Representatives are known from the Upper CretaceousThe Cretaceous period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic period (about 135 mya) to the beginning of the Paleocene epoch of the Tertiary period (65 mya). The end of the Cretaceous also defines the and PaleoceneThe Paleocene epoch (64-58 mya) ("early dawn of the recent") is the first geologic epoch of the Tertiary period in the modern Cenozoic era. As with most other older geologic periods, the strata that define the epoch's beginning are well identified, but th of North America.
