There may be only one species, Blastomeryx gemmifer. == Description == Blastomeryx was long and looked like a modern chevrotain. Its canines were elongated into tusks which it probably used to uproot plants and fend off predators. While Blastomeryx (as well as modern musk deer) lacked antlers, a Middle Miocene species had bony knobs on its skull, which have been interpreted as incipient horns. Blastomeryx had a reduced radius and ulna, as well as fully formed cannon bones, like modern deer.
== History == In older literature, Blastomeryx has been placed within Cervidae proper, though this affinity is generally not believed. Edward Drinker Cope and William Diller Matthew were of the belief that Blastomeryx descended from Hypertragulids, assuming the genus was indigenous and not a result of any migration.
