Uarbryichthys is a genus of primitive ginglymodianray-finned fish from fossil beds near the Talbragar River Bed. The various species were lake-dwelling fish that lived during the Upper Jurassic of Australia, and are closely related to the macrosemiids. The living animal would have had a superficial resemblance to a very small porgie, scup, or sea bream, but with a heterocercal tail fin.
