The Cotswold–Severn Group long barrows usually contained human bone in large quantities, with said barrows averaging the remains of between 40 and 50 individuals each. In some cases, the individual corpses may have been placed into the chamber whole and then left to decay inside; in others, the body may have been dismembered or
excarnated outside the barrow before the bones were then placed into the chamber. Usually, the bones of different individuals were jumbled up within the chambers of the tomb, perhaps reflecting a deliberate decision to symbolically merge the individual with the collective dead. In some cases, the bones were segregated into different chambers within the tomb according to age or sex. In most cases, such deposits of human bone were made successively, at various intervals. It is also apparent that in some cases, select bones appear to have been removed from the chambers, perhaps for use in ritualised practices. When entering the chambers to either add or remove new material, individuals would likely have been exposed to the smell of decaying corpses. It is unknown if entering this area was therefore seen by Early Neolithic Europeans as an ordeal to be overcome or an honourable job to be selected for. In a few instances, other items were deposited in the chambers with the human bone. Such deposits included pottery, worked flint, pebbles, stone discs, beads, bone pins, dog bones, and most prominently, cattle bone. The deposition of animal bone—especially the skulls of cattle and pigs—was also a common recurring factor in the forecourts of the Cotswold-Severn long barrows. The purpose of these is not known; they may have represented
totemic animals, have been seen as protective deposits, or been the remains of feasts. ==Meaning and purpose==
