Hemimachairodus

Hemimachairodus is an extinct genus of machairodontine (sabre-toothed) cat with only one species, Hemimachairodus zwierzyckii, known from only a few fossils from the Pleistocene of Java. Other fossils attributed to Hemimachairodus sp. are known from the Villafranchian (late Pliocene to early Pleistocene) of Tajikistan.

==Discovery and naming== The species was originally described in 1934 by German palaeontologist Gustav Heinrich Ralph von Koenigswald under the name Epimachairodus zwierzyckii. He referred to it again by that name in 1940. A 1962 paper by Bjorn Kurtén referred to it as Homotherium zwierzyckii, stating that its homotheriine affinities were unmistakable, although he allowed it might also belong to the homotheriine genus Dinobastis instead.
