Near the top of these trenches, Beaker pottery was found. Two small trenches, labelled F1 and F2 on the diagram, were dug at the top of the slope, but found no evidence that the bank and ditch had ever extended around the enclosure's northern side. Trench G produced a few sherds and some struck flint; these were all lost by the time Drewett evaluated the results of the dig, but he suggested that the pottery was probably Romano-British, since it was found not far below the turf line. Later investigations In May 1983, Rodney Castleden, a Sussex resident walking on Combe Hill, found a carved chalk item partly exposed through the turf in the middle of the enclosure. The object was examined by Alan Thompson, who was researching prehistoric carved chalk finds from Sussex. Thompson suggested it may have been a half-completed carving of a phallic symbol: it was roughly rectangular in cross-section, narrowing towards one end, with incised lines on two sides. Thompson could not determine what tool had been used to carve the chalk, or the age of the item, though he cites another phallic-shaped chalk find from Itford Hill in Sussex which was considered to be from the Bronze Age. In Drewett's 1994 review he commented that since the item had not been found in the 1962 dig, which had dug a trench (labelled D on the site plan) at the spot where the item was found, it might have been carved in 1962 and left at the site. The Royal Commission on the Historical Monuments of England included Combe Hill in a 1995 survey of multiple sites. The resulting report, by Alastair Oswald, concluded that Thomas's conclusions from snail shell evidence from Musson's excavation were consistent with most of the Neolithic enclosures in Sussex: the evidence available for all but two of the other sites indicates they were probably constructed in small clearings in woodland. The two exceptions are The Trundle and Whitehawk Camp, both thought to have been constructed at a time when the woodland had already been cleared. In 2003, Brighton & Hove Archaeological Society commissioned a resistivity survey of the site. The survey was hampered by dry weather, limiting the quality of the data, but the inner circuit and the western arc of the outer circuit were both detected. Clusters of post-holes were found in the south and east of the inner enclosure,
