Palaeochiropterygidae was merged into Archaeonycteridae by Kurten and Anderson in 1980, but modern authorities specializing in bat fossils maintain the distinction between the two. [ 1 ] [ 2 ] It was classified to the unranked clade Microchiropteramorpha by Smith et al. in 2007.
[1] [2] The family Palaeochiropterygidae was also merged into Archaeonycteridae by Kurten and Anderson, but modern authorities specializing in bat fossils maintain the distinction between the two. [3] [4] They existed from the Ypresian to the Lutetian ages of the Middle Eocene epoch (55.8 to 40.4 million years ago). [1]

The 2003 discovery of an early fossil bat from the 52-million-year-old Green River Formation, Onychonycteris finneyi, indicates that flight evolved before echolocative abilities. [27] [28] Onychonycteris had claws on all five of its fingers, whereas modern bats have at most two claws on two digits of each hand.

In addition, several fossil genera are known; the oldest fossils attributed to the family are from the middle Eocene of Europe. [4] In their 1997 Classification of Mammals , Malcolm C. McKenna and Susan K. Bell proposed a division of Hipposideridae (called Rhinonycterinae in their work) into three tribes , one with two subtribes, [ 5 ] but ...
