Fossils of Prolibytherium were found in the Marada Formation of Libya, Vihowa Formation of Pakistan, and the Moghara Formation of Egypt.[1] DescriptionThe {{convert|1.80|m}} long creature would have superficially resembled an okapi or a deer. Unlike these, however, Prolibytherium displayed dramatic sexual dimorphism, in that the male had a set of large, leaf-shaped ossicones with a width of {{convert|35|cm}}, while the female had a set of slender, horn-like ossicones.[2] The taxonomic status of Prolibytherium remains in flux. At one time, it was described as a relative of Sivatherium (as a precursor to "Libytherium maurusium" (S. maurusium)). Later, it would be regarded as a palaeomerycid, or either as a climacoceratid, or as a basal member of Giraffoidea. With the discovery and study of a female skull in 2010, Prolibytherium is tentatively regarded as a climacoceratid.[2] References{{portal|Paleontology|Neogene|Prehistoric mammals|Prehistory of Africa|Prehistory of Asia}}1. ^{{cite web |url=http://fossilworks.org/?a=taxonInfo&taxon_no=42706 |title=Prolibytherium |website=Fossilworks |accessdate=13 June 2014 }} {{Commons category|Prolibytherium}}{{Wikispecies}}{{Taxonbar|from=Q729196}}{{paleo-eventoedungulate-stub}}2. ^1 {{cite journal | first1 = Israel M. | last1 = Sánchez | first2 = Victoria | last2 = Quiralte | first3 = Jorge | last3 = Morales | first4 = Beatriz | last4 = Azanza | first5 = Martin | last5 = Pickford | title = Sexual dimorphism of the frontal appendages of the early Miocene African pecoran Prolibytherium Arambourg, 1961 (Mammalia, Ruminantia) | journal = Journal of Vertebrate Paleontology | volume = 30 | issue = 4 | date = 2010 | pages = 1306–1310 | doi = 10.1080/02724634.2010.483555 | jstor = 40864406 }} 9 : Climacoceratidae|Prehistoric mammal genera|Mammalian incertae sedis|Miocene mammals of Africa|Fossils of Egypt|Fossils of Libya|Miocene mammals of Asia|Fossils of Pakistan|Fossil taxa described in 1961 |
