The rock carvings of Southern Scandinavia are generally dated to the middle and later part of the Bronze Age, c. 1500-500 BC. Occasionally, more absolute dating of single panels or figures can be made, based on typological or stylistic features of the image, and by comparisons with identifiable objects. The Fossum panel can be dated by the male human figures equipped with shields of so called "Hallstatt-type", to the Later Bronze Age c. 1000-500 BC.
