Helmeted frogs with co−ossified skulls (Thaumastosaurus) were previously known in Europe only in the Eocene on the basis of Thaumastosaurus bottii from southwestern France and Thaumastosaurus wardi from coastal southern England. We describe Thaumastosaurus sulcatus, that differs from these species in having a different dermal sculpture pattern and tooth morphology. We suggest that the auburn colored tooth crown tips in T. sulcatus, as in some other vertebrates, reflect extra hardness for protection against tooth wear. Autochthonous Thaumastosaurus species in southern England support the concept that southern England and southwestern France were distinct faunal provinces in the Late Eocene.
