Problastomeryx primus

Mammalia - Moschidae

Taxonomy

Blastomeryx primus was named by Matthew (1908). Its type specimen is A.M. 13822, a partial skeleton (fairly complete skull and jaws with limbs and feet, and a few vertebrae), and it is not a trace fossil.

It was recombined as Parablastomeryx primus by Frick (1937); it was recombined as Problastomeryx primus by Webb (1998), Prothero (2007) and Prothero (2008).

Synonyms

Blastomeryx mollis was named by Merriam (1911). Its type specimen is UCMP 11564, a mandible, and it is a 3D body fossil. Its type locality is Virgin Valley, which is in a Barstovian terrestrial horizon in the Virgin Valley Formation of Nevada.

It was recombined as Nemomeryx mollis by Morea (1981); it was synonymized subjectively with Problastomeryx primus by Prothero (2011).
Blastomeryx olcotti was named by Matthew (1908). Its type specimen is A.M. 13224, a partial skeleton (upper and lower jaws, hind limbs, and feet), and it is not a trace fossil. Its type locality is Blastomeryx olcotti type locality, which is in a Harrisonian terrestrial horizon in Wyoming.

It was recombined as Parablastomeryx olcotti by Frick (1937); it was recombined as Problastomeryx olcotti by Webb (1998); it was synonymized subjectively with Problastomeryx primus by Prothero (2007) and Prothero (2008).
