Field collected data on adult common frogs from 11 locations along a 1600 km latitudinal gradient from southern Sweden to northern Finland. Ages of collected individuals were estimated with skeletochronological methods in laboratory. Available are also e.g. body sizes (snout-vent lenghts) and weighs of the individuals.
