Extensively illustrated report on an excavation in Oxfordshire near the Iron Age hillfort at Segsbury. Ephemeral traces of Mesolithic and Neolithic activity, including a possible Neolithic timber structure, were found. The remains of a probable Late Bronze Age pit alignment were also found. Small Iron Age settlements comprising round houses, pits and other structures, and burials were revealed. One particular burial in a pit had been subjected to unusual treatment that included the removal of the individual's feet after death. Small Roman and post-Roman cemeteries also were identified. The small Late Roman cemetery included males, females and neonates. This cemetery is typical for the period and the burials were accompanied by a range of artefacts including coins, brooches, a bracelet and rings as well as an unusual fragmentary double-sided bone or antler comb with a horse motif and ring-and-dot decoration. A small undated cemetery was originally believed to be either of Roman or less likely post-Roman date. However, radiocarbon dating revealed the unaccompanied burials to be of late 7th or early 8th century AD date. Innovative scientific techniques including radiocarbon dating and Bayesian modelling, aDNA and isotope analysis have revealed some important details such as familial relationships and dating that would not otherwise have been known. Small assemblages of finds included worked flint and prehistoric pottery, Roman and later pottery, worked bone, glass and metalwork.
