Occurrence of the Gomphotherium angustidens group in China, based on a revision of Gomphotherium connexum (Hopwood, 1935) and Gomphotherium shensiensis Chang and Zhai, 1978: continental correlation of Gomphotherium species across the Palearctic
In this paper, we restudy previously reported material of
Gomphotherium connexum
and
G.
shensiensis
from China.
G. connexum
is characterized by the strong posterior pretrite central conules of the upper molars, which are larger than the corresponding anterior ones (at least in the second loph), the narrow interloph(id)s, the high central conules, and the narrow contour of m3.
Gomphotherium
cf.
shensiensis
(here is attributed to
G. connexum
) from the Junggar Basin is more derived than the type material of
G. connexum
in larger size and heavier cementum.
G. connexum
is very similar to
G. angustidens
, which was widely distributed in the Middle Miocene (MN6–8) of Europe.
Gomphotherium
shensiensis
(here is attributed to
G.
cf.
subtapiroideum
) shows crest-like elements in the teeth crowns. The posttrite lophs are subdivided and anteroposteriorly compressed, and the interlophs are relatively anteroposteriorly wide. These features are similar to
G. subtapiroideum
, which occurred in the later Early Miocene to the earlier Late Miocene (MN5–9) of Europe. This revision of Chinese
Gomphotherium
demonstrates strong similarities in
Gomphotherium
species between eastern and western Eurasia, representing a continental diffusion of
Gomphotherium
species across the Palearctic region.
