Pterodon (mammal)
''Pterodon'' ("winged tooth") is an extinct genus of superficially wolf-like hyainailurids from subtribe Pterodontina within polyphyletic tribe Hyainailourini in paraphyletic subfamily Hyainailourinae, that lived in late Eocene Europe. Classification and phylogeny Taxonomy ''Pterodon nyanzae'' is now considered to be synonymous with ''Hyainailouros''.Lewis, M. E., Morlo, M. (2010.): "Creodonta". – In : Werdelin, L., Sanders, W.

University of California Press, Berkeley, pp. 543–560. https://doi.org/10.1525/california/9780520257214.003.0026 Likewise, the putative Asian species ''P. dahkoensis'' is now assigned to its own genus, ''Orienspterodon''.

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Apterodontinae
Apterodontinae ("without winged tooth") is an extinct subfamily of hyainailourid hyaenodonts that lived in Africa and Europe during the late Eocene to middle Oligocene The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the ....
