Шаблон:Short description Шаблон:Automatic taxobox
Icaronycteris is an extinct genus of microchiropteran (echolocating) bat that lived in the early Eocene, approximately Шаблон:Mya, making it the earliest bat genus known from complete skeletons, and the earliest known bat from North America.[1][2] Multiple exceptionally preserved specimens, among the best preserved bat fossils, are known from the Green River Formation of North America.[1][2] The best known species is I. index.[3] Fragmentary material from France has also been tentatively placed within Icaronycteris as the second species I. menui.[4] I. sigei is based on well-preserved fragments of dentaries and lower teeth found in Western India.[5] In 2023, the species I. gunnelli also from the Green River Formation was distinguished from I. index, and I. menui and I. sigei were proposed to be removed from the genus due to them not being closely related.[2]
Description
Icaronycteris[6] measured about Шаблон:Convert long and had a wingspan of Шаблон:Convert. It closely resembled modern bats, but had some primitive traits. The tail was much longer and not connected to the hind legs with a skin membrane, the first wing finger bore a claw and the body was more flexible. Similarly, it had a full set of relatively unspecialised teeth, similar to those of a modern shrew. Its anatomy suggests that, like modern bats, Icaronycteris slept while hanging upside down, holding onto a tree branch or stone ridge with its hind legs.[7]
Phylogeny
According to Шаблон:Harvnb,[8] Icaronycteris is the first genus, followed by Archaeonycteris, Hassianycetris, and Palaeochiropteryx, in a series leading to extant microchiropteran bats.[9]
Шаблон:Harvnb found Onychonycteris to be sister to the North American species of Icaronycteris.
