Ordo: Perissodactyla
Familia: Brontotheriidae
Name
Palaeosyops Eometarhinus – Wikispecies link – Pensoft Profile
- Palaeosyops Mader, Bryn J., 2010, Zootaxa 2339: 15-16.
Diagnosis
Diagnosis: Same as for member genus, Palaeosyops (see below). Sister taxon to all brontothere subfamilies except for the Eotitanopinae (see cladogram in Mader 1998, Fig. 36.5)
Discussion
Discussion:Palaeosyops is the sole member of the Palaeosyopinae (Steinmann & D derlein 1890). Because the subfamily Palaeosyopinae consist of only a single genus, the diagnosis of the subfamily does not differ from that of its member genus.
Description
However, according to Article 11.7. 1.2, in order for a family group name to be valid, it must be clearly used by the original author to "denote a suprageneric taxon and not merely as a plural noun or adjective referring to the members of a genus...". The name Limnohyinae is invalid, therefore, because it is not clear from the context of Marsh's paper whether the term Limnohyidae was intended to apply to Limnohyus and some of the other brontothere genera then recognized (such as Palaeosyops and Telmatherium), or merely to the three species of Limnohyus described by Marsh and Cope up to that time.
