Bahndwivici ammoskius (Conrad 2006a) Green River Formation, early Eocene FMNH PR2260 was originally considered a shinisaurid anguimorph. Here Bahndwivici was derived from a sister to Yabeinosaurus and nests at the base of the varanoids including Shinisaurus, Varanus and Tylosaurus.
Distinct from Yabeinosaurus, Bahndwivici was much smaller. The tail had ossified dermal scales.
