Middle Neolithic pits

Broadly contemporary with the monuments were up to one hundred Middle Neolithic pits. These were found across both sites, many of them in small groups. Most of them were similar in form, being circular in shape and about 1 metre wide. 
Many of them contained finds, most notably Middle Neolithic Peterborough Ware pottery and worked flints, including fragments from polished flint axes, as well as pieces of burnt flint, fired clay, animal bone and non-local stone. 
However, while some contained large quantities of finds which appeared to have been deliberately placed, and with some care, others contained very little material, and some contained none, although it is possible that organic objects had been deposited which have since decayed.
Almost 20 kilograms of Peterborough Ware was recovered during the excavations, most of it from these pits. The vessels belong to the highly decorated Mortlake substyle, in a range of bowl and jar forms. 
Among the stone objects were a number of pieces of naturally perforated flint. Neolithic mace-heads made of similar stones have been found in the River Thames around London.
It is not clear what these pits were dug for, but they demonstrate that people were visiting and re-visiting this part of the landscape.
