Tetrapod postcranial bones are described from Scotland: from the Limestone Coal Group (Early Carboniferous, Serpukhovian) at the Dora open cast site, Fife, and from beds equivalent to the Burdiehouse Limestone (Early Carboniferous, Visean) on the island of Inchkeith, Firth of Forth. The elements from Dora are derived relative to Devonian and Tournaisian tetrapods in having a diamond-shaped interclavicle with no parasternal process, a humerus with a triangular-shaped entepicondyle, a rod-like ilium lacking a post-iliac process and a gracile femur with a prominent internal trochanter but no adductor blade. These bones share characters with their homologues in colosteids and temnospondyls and may be attributable to Doragnathus woodi. The femur from Inchkeith most closely resembles that of the embolomere Proterogyrinus scheelei.
