This anomodont was discovered in Kotelnich on the Vyatka River Russia. It was found in sandstone sediment, so it most likely was a delta-dwelling species, but this is not conclusive, as the specimen may have been washed downriver, away from its habitat. S. getmanovi has teeth that are heavily abraded, suggesting a diet consisting of plant material with a high silica content. More recently found fossils indicate that it led an arboreal lifestyle. FeaturesThe 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 eye socket 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.[1] See also
