Changes in diversity of Artiodactyla
from the Pliocene to Middle Pleistocene
of northern Eurasia are considered. The
major turnovers of artiodactyl communities
correlate with the major global cooling
events at the boundaries of epochs
and ages and were accompanied by migrations.
A correlation of the main biotic
events in northern Eurasia and adjacent
areas is presented. Zoogeographical features
of Artiodactyla evolution in northern
Eurasia and the role of Artiodactyla
in the establishment of different bioms
are addressed.

A comparative study of the Late
Pleistocene Egorov’s narrow-skulled
vole from the Indigirka River basin is
performed. The taxon was previously
regarded as a subspecies of Microtus
(Stenocranius) gregalis (Pallas, 1779).
Based on a number of morphological
characters, it is shown that this vole is
closer to the American species Mynomes
(Vocalomys) miurus (Osgood, 1901). It
is proposed that Mynomes (V.) miurus
egorovi (Fejgin in Baranova et Fejgin,
1980) penetrated into northeastern Siberia
during the Zyryanian glacial.

Seven main stages in the evolution of
Pliocene-Pleistocene artiodactyl communities
from Russia, Ukraine, Moldova,
Georgia, Kazakhstan, and Tajikistan
within the interval from 5.3 through 0.4
Ma are characterized. The dominant
groups are briefly revised. The major
biotic events and the development of the
main phyletic lineages are discussed.

Parailurus 一 新 种 = A new species of
lesser panda Parailurus (Mammalia,
Carnivora) from the Pliocene of Transbaikalia
(Russia) and some aspects of

A new species of the lesser panda,
Parailurus baikalicus sp. nov., from the
Pliocene of Transbaikalia is described.
In contrast to the European taxa P. anglicus
and P. hungaricus, it retains a
primitive occlusal pattern of M 1 -M 2 ,
with a concave buccal outline, small
mesostyle on M 1 , and undeveloped
styles on M 2 . At the same time, the
Transbaikalian panda is more advanced
than other representatives of Parailurus
in the upper molars with a reduced lingual
cingulum and an enlarged paraconule,
which is partially (M 1 ) or completely
(M 2 ) separated from the protocone.
This combination of primitive and
advanced characters points to the separation
of the Asian branch at the earliest
stages of the genus development. The
Transbaikalian lesser panda may represent
a terminal form of this phylogenetic
lineage.
