According to Simmons & Geisler 1998, [7] Icaronycteris is the first genus, followed by Archaeonycteris, Hassianycetris, and Palaeochiropteryx, in a series leading to extant microchiropteran bats. [8] Rietbergen et al. 2023 found Onychonycteris to be sister to the North American species of Icaronycteris.
Palaeochiropteryx (/ ˌ p æ l i oʊ k aɪ ˈ r ɒ p t ər ɪ k s / PAL-ee-oh-ky-ROP-tər-iks) is an extinct genus of bat from the Middle Eocene of Europe and North America.It contains three very similar species – Palaeochiropteryx tupaiodon and Palaeochiropteryx spiegeli, both from the famous Messel Pit of Germany, as well as Palaeochiropteryx sambuceus from the Sheep Pass Formation (Nevada ...

The two oldest-known fossil skeletons of bats, unearthed in southwestern Wyoming and dating to at least 52 million years ago, are providing insight into the early evolution of these flying mammals ...
Onychonycteris finneyi was the strongest evidence so far in the debate on whether bats developed echolocation before or after they evolved the ability to fly. O. finneyi had well-developed wings, and could clearly fly, but lacked the enlarged cochlea of all extant echolocating bats, closely resembling the old world fruit bats which do not echolocate. [1]
Palaeochiropteryx tupaiodon is the most common mammal found at Messel. An additional species of Palaeochiropteryx, P. sambuceus, has been described from the middle Eocene of North America. [4] All other species belonging to Palaeochiropterygidae are known only from isolated teeth and jaw fragments from Europe, India, Turkey, and possibly North ...
