Graulia is an extinct genus of lobe-finned fish from the Middle Triassic (Ladinian) of eastern France. It contains a single species, G. branchiodonta, and is represented by some of the most well preserved fossils of any Mesozoic coelacanth. Discovered in the Muschelkalk, two specimens are known, both of which are 16 cm long juveniles.^[1]

The genus name Graulia is a reference to Graoully, a mythical dragon from the folklore of Lorraine, France, where the specimens were found. The species name branchiodonta, comes from the Greek words βράγχια "gills" and ὀδούς, ὀδόντος "tooth", the latter which refers to the large teeth of the ceratobranchials.^[1]

Graulia had very small teeth in its jaws, but the ceratobranchials contained much larger teeth that would have functioned similarly to the gill rakers seen in ray-finned fish. As a result, Graulia is inferred to have been a suction feeder. Enlarged sensory canals in the skull suggest strong sensitivity to minimal water changes. This, in addition to the streamlined skull and relatively large fin, support that Graulia lived a highly active predatory lifestyle.^[1]
