Blastomeryx is an extinct genus of musk deer of the family Moschidae, subfamily Blastomerycinae, endemic to North America during the Oligocene-Miocene epochs (24.8—10.3 mya), existing for approximately 14.5 million years.[1] There is only one species, Blastomeryx gemmifer.[2]

Morphology

It was 75 cm (2 ft 6 in) 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 most species of Blastomeryx (as well as modern musk deer) lacked antlers, a Late Miocene species had bony knobs on its skull, which have been interpreted as incipient horns.[3]

Body mass

Two specimens were examined by M. Mendoza for body mass. The first specimen was estimated to have a weight of Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value).. The second specimen was estimated to have a weight of Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value)..[4]
