 Significantly, this is the only postcranial element of "Homo Heidelbergensis" to have been found in Northern Europe (in other words, coming from anywhere other than the skull).The tibia is extremely robust for its size and may be an indication of high running activity, presumably in tracking an animal after it has been speared.Both ends of the bone show signs of gnawing, possibly by a wolf, suggesting that perhaps the Boxgrove hominids were sometimes prey to other animals.
