The Tamar Group is an early Devonian to early Carboniferous geologic group in south Devon and north Cornwall in southwest England . The name is derived from the valley of the River Tamar on the Devon/Cornwall border. The Group comprises (in ascending order) the Torquay Limestone, Tavy and Burraton formations.[1] Some of the rocks are fossiliferous.
