Name: Pterodon ‭(‬Wing tooth‭)‬.
Phonetic: Teh-roe-don.
Named By: Blainville‭ ‬-‭ ‬1839.
Classification: Chordata,‭ ‬Mammalia,‭ ‬Creodonta,‭ ‬Hyaenodontidae.
Species: P.‭ ‬dasyuroides‭ (‬type‭)‬,‭ ‬P.‭ ‬africanus,‭ ‬P.‭ ‬hyaenoides,‭ ‬P.‭ ‬syrtos.
Diet: ‭ ‬Carnivore.
Size: Unavailable.
Known locations: Egypt,‭ ‬France,‭ ‬Pakistan,‭ ‬United Kingdom.
Time period: Usually Late Eocene to Early Oligocene.‭ ‬Fossils from Pakistan indicate as late as Serravalian of the Miocene.
Fossil representation: Remains of several individuals.

       One of the creodont mammals that were most common from the Paleocene to Oligocene periods,‭ ‬Pterodon seems to have been most numerous around Europe and North Africa.‭ ‬An odd set of remains from Pakistan however not only increases the geographic range of this creodont,‭ ‬but also the temporal range as well.‭ ‬Being interpreted as coming from the Serravalian stage of the Miocene,‭ ‬these fossils indicate that the Pterodon genus survived for approximately fifteen million years after the early Oligocene.‭ ‬Although unusual,‭ ‬this is not actually the first,‭ ‬or is‭ ‬likely to‭ ‬be the last time that an extinct animal is realised to have had a significantly longer temporal range than first thought.
