Bunostegos akokanensis (Sidor et al. 2003, Tsuji et al. 2013; Late Permian, 1.5m; MNN-MOR47, Fig. 1) is a large pareiasaur nesting close to small Elginia (Newton 1893) in the large reptile tree (640 taxa), closer to turtles than most other pareiasaurs. Analysis of the limb bones suggested a more upright stance than is typical for pareiasaurs and turtles. It lived in a desert environment. The specimen is known from parts of several specimens.
