Myotragus (Neo-Latin, derived from the Greek: μῦς, τράγος "mouse-goat") is an extinct genus of goat-antelope in the tribe Caprini which lived on the Balearic Islands of Mallorca and Menorca in the western Mediterranean until its extinction around 4,500 years ago.[1] The fossil record of Myotragus on the Balearic Islands extends over 5 million years back to the early Pliocene on Mallorca, where it presumably arrived after the evaporation of the Mediterranean Sea during the Messinian Salinity Crisis.

Myotragus is represented by six sequential chronospecies representing gradual change in morphology. The youngest and best known species, M. balearicus, is noted for a number of unusual morphological adaptions, including forward facing eyes suggestive of binocular vision, as well as a long lifespan, which developed in an unusual ecosystem where only a few other mammal species were present, terrestrial predators were absent, and Myotragus functioned as the only major herbivore. M. balearicus became extinct when humans arrived in the Balearic Islands during the 3rd millennium BC.

Early genetic research suggested that it was closely related to sheep of the genus Ovis;[2] however, more recent research has indicated that its closest living relative is the takin (Budorcas taxicolor).[3]
