The partial left jaw ramus of a large amphibian, from the Low Main Seam (Middle Coal Measures) of Newsham, Northumberland, is described for the first time. It is attributed to Anthracosaurus russelli Huxley and represents a previously unknown region of the jaw. The surangular crest is unlike that of other embolomerous anthracosaurs, the articular is widely exposed and the surangular restricted anteriorly by the depth of the adjacent dentary. The long posterior coronoid bears teeth of characteristic form and structure. A new restoration of the whole jaw of Anthracosaurus is presented. Anatomical differences from that of other embolomeres can be correlated with the massive dentition and long shallow suspensorium of Anthracosaurus.
