Two recent synapsid papers with new taxa:


M. F. Ivakhnenko (2012)
Permian Cynodontia (Theromorpha) of Eastern Europe
Paleontological Journal 46(2): 199-207

A collection of Cynodontia from the Permian of Eastern Europe is
revised. The taxonomic position of a number of previously described
forms is reconsidered. New taxa, Novocynodon kutorgai gen. et sp. nov.
(Thrinaxodontidae) from the Middle Permian and Sludica bulanovi gen.
et sp. nov. (Procynosuchidae) from the Upper Permian, are described.

Dicynodontids of Eastern Europe.

Dicynodontids are the most widespread and diverse group of higher
anomodonts in the Late Permian of Eastern Europe. Dicynodon
trautscholdi Amalitzky, 1922 is the first dicynodont described in
Russia (Amalitzky, 1922). The taxonomic position of this and several
closely related forms described by V. P. Amalitzky and P. P. Sushkin
(Sushkin, 1926) remains an open question. A reexamination of cranial
morphological features in East European members of the family
Dicynodontidae allows the assignment of Dicynodon trautscholdi to a
new genus, Fortunodon gen. nov., and corroborates the isolated
position of Dicynodon amalitzkii established by Sushkin (1926), which
is also assigned to the genus Fortunodon gen. nov. Beginning from the
Sokolki Assemblage, Late Permian dicynodontids adapted to various
ecological niches and had a noticeable effect on the general
appearance of the tetrapod fauna.
