Paramachairodus (alternately Paramachaerodus) is an extinct genus of saber-tooth cat of the subfamily Machairodontinae, which was endemic to Europe and Asia during the late Miocene from 15 to 9 Ma.[2]

Paramachairodus is one of the oldest known true saber-toothed cats. A large number of fossils were discovered in Cerro de los Batallones, a Late Miocene fossil site near Madrid, Spain. One leopard-sized species is known, Paramachairodus orientalis from the Turolian. A second species, Paramachairodus maximiliani, has been considered a synonym of Paramachairodus orientalis by some authors,[3] but was considered a valid species in the most recent systematic revision.[1] That revision, based on an extensive morphological analysis, also determined that the species P. ogygia exhibited less derived sabertooth features than the other Paramachairodus species and should be assigned to a separate genus, Promegantereon.[1][4]

The animals were about 58 centimetres (23 in) high at the shoulder, similar to a leopard, but with a more supple body. The shape of its limbs suggests that it may have been an agile climber, and could have hunted relatively large prey.[5]
