==History and taxonomy== The species Felis ogygia was first described by Kaup in 1832. In 1938, Kretzoi proposed moving it to the new genus Promegantereon. It was also thought to have been a species of Paramachairodus, however further analysis found that due to its more primitive morphology as evidenced by Salesa et al. in 2002 with an in-depth description of its anatomy, Promegantereon ogygia is believed to be its own genus and species and therefore should be separate from Paramachairodus.
