Suminia getmanovi was a
species of
stem-mammal, in the
clade Anomodontia, which lived 260 million years ago in the late
Permian ("zone II"). This
anomodont was discovered in
Kotelnich on the
Vyatka River Russia. It is found in
sandstone sediment, so most likely represents a
delta-dwelling species, but this is not conclusive, as the specimen may have been washed down river, away from its habitat.
S. getmanovi has teeth that are heavily abraded, suggesting plant material of high
silica content. More recently found fossils indicate that it led an
arboreal lifestyle.
