[[File:Onychonycteris finneyi Fossil Butte National Monument.jpg|thumb]] [[File:Onychonycteris NT small.jpg|thumb|Artists impression what the animal might have looked like]] '''Onychonycteris''' is an extinct [[genus]] of [[bat]], which lived during the [[Eocene]] period, 52.5 million years ago, in the area that is now [[Wyoming]]. One species has been described, ''Onychonycteris finneyi.'' Using this species, it could be shown that these primitive bats first developed the ability to fly, before they had echolocation.<ref>Nancy B. Simmons, Kevin L. Seymour, Jörg Habersetzer und Gregg F.
