Bahndwivici ammoskius (Conrad 2006a) Green River Formation, early Eocene FMNH PR2260 was originally considered a shinsaurid anguimorph. That may be true, but it has not been tested. Here Bahndwivici nests at the base of the varanoids, Varanus, snakes and their kin. Cryptolacerta was a sister and both were derived from a sister to Carusia and Yabeinosaurus.
Distinct from Cryptolacerta, the vertebrae were shorter, especially so posteriorly. The scapulocoracoid was not fenestrated. The hands and feet were relatively larger.
