Bauersaurus is an extinct genus of pan-gekkotan lizard from the late Ypresian or early Lutetian of France.

It is known from a single species, Bauersaurus cosensis.

It is only known from fragments of the upper (maxilla) and lower jaw).

Remains of the species were collected from the Quercy Phosphorites, fissure filling deposits found in the Quercy region of France.

[2] Based on the similarity of its maxillary morphology to Eichstaettisaurus, the authors of the describing paper propoesed that B. cosensis likely represents a ghost lineage of Pan-Gekkota that survived the Cretaceous-Palaeogene extinction event and persisted into the Eocene in Europe, either like Eichstaettisaurus outside crown Gekkota or within the Gekkota crown group.
