Gazella psolea is an unusual prehistoricspecies of gazelle that lived in Africa and Arabia; it is only known from fossils. It makes up the subgenusDeprezia due to its unique skull morphology: it had a long premolar row, and its nasal area is peculiar, with short nasal bones and a very large nasal opening. It therefore seems to have been able to breathe cold and dry air (a similar adaptation as found in the saiga), but why this feature evolved is still rather mysterious. Perhaps it made seasonal migrations to the High Atlas mountains, where such an adaptation would have been useful.
