Suminia
''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. ==Features== The teeth were quite large for its size containing a single cusp per tooth with many serrations as in a serrated knife. These teeth were replaced throughout its life cycle. The eyesocket was fairly large and placed near the temporal opening, separated by a thin postorbital bar. ''Suminia'' had grasping hands, which has led researchers to conclude that it was a tree-climbing animal, the earliest known such vertebrate species found thus far.〔(Field Museum scientist describes first vertebrate to live in trees )〕
