Comments
MkTn-4: It yielded one of five bones that were submitted for dating to ascertain the length of time before which fresh, unburned large mammal bone would be affected by the acidic soils of the boreal forest. The bones had simply been discarded on the surface and slowly incorporated into the sod/humus. The results suggest that fresh mammal bone can persist for up to 300 years without significant alteration. Under specific burial conditions, such bones may persist with little change for at least 600 years.
