Alexandra Bayliss is a British archaeologist and academic. She is Head of Scientific Dating at Historic England, [2] and a part-time Professor of Archaeological Science at the University of Stirling in Scotland. [1] Her research focuses on the construction of exact chronologies of European Neolithic archaeological sites, through the application of Bayesian statistical modelling of radiocarbon dates.

Contents

Partnered with Alasdair Whittle from Cardiff University, Bayliss has conducted extensive research on causewayed and related enclosures in the United Kingdom and Ireland. The results of that study, a book co-authored by Bayliss, Whittle and Frances Healey, Cardiff University, titled Gathering Time: dating the early Neolithic Enclosures of Southern Britain and Ireland was named the British Archaeological Awards book of the year in 2012.

From 2012 to 2017, Bayliss and Whittle led a project funded by the European Research Council (ERC). The project named "The Times of Their Lives" was a series of studies in precise chronologies and their implications, across several regions and phases of Neolithic Europe. [3]

Bayliss has conducted research on additional historic sites in the United Kingdom, Europe and Turkey, using the same methodology of statistical modelling of radiocarbon dates. [4]

Education

Bayliss obtained a BA (Honours) and a PhD at University College London. [1]

Archaeological career

Since 2000, Bayliss and Whittle have collaborated on a number of research projects pertaining to the chronology of archaeological sites. Their initial study examined early Neolithic long barrows in Southern England. Additional studies focused on causewayed enclosures in the UK and Ireland. [4]

Starting in 2012 and continuing until 2017, Bayliss and Whittle led a series of studies funded by the European Research Council. The project, named The Times of their Lives: Towards precise narratives of change in the European Neolithic through formal chronological modelling, consisted of a number of investigative studies using Bayesian chronological modelling of archeological sites across Europe, from the 6th to the 3rd century BC. Case studies were conducted in Spain, Malta, France, Germany, Switzerland, Poland, Hungary, Serbia, Romania, Scotland and England. [4]

One of the studies undertaken as part of theTimes of Their Lives project, was an investigation into the development of Neolithic settlements in Orkney, Scotland. The findings of the study, co-authored with Professor Colin Richards of the University of the Highlands and Islands Archaeology Institute, and published in Antiquity journal, challenge the previously determined timeline for prehistoric life on Orkney. [5]

Bayliss is currently working on a long-term research project at a Neolithic settlement in Çatalhöyük, Turkey. The study, led by Professor Ian Hodder, from Stanford University, is funded by a grant from the UK Arts and Humanities Research Council and the US National Science Foundation. Bayliss's work involves investigating the structures and spaces uncovered by the archaeological site's 1960s excavations and compiling a detailed, multi-generation chronology of the site. [6]

In a study recently conducted by Historic England at the prehistoric site of Avebury, Bayliss's research revealed that two prehistoric timber circles are 800 years older than previously thought. The wooden structures, 20 miles north of Stonehenge, extend over 4 km (2.5 miles) and were built with more than 4,000 trees. Applying current radiocarbon dating techniques to charcoal samples. Bayliss was able to determine that the wooden circles were built in 3300 BC, instead of the 2500BC as estimated earlier. [7]

<span class="mw-page-title-main">Mesolithic</span> Prehistoric period, second part of the Stone Age

The Mesolithic or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and Middle East, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in the Middle East roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa.

<span class="mw-page-title-main">Henge</span> Type of Neolithic earthwork

There are three related types of Neolithic earthwork that are all sometimes loosely called henges. The essential characteristic of all three is that they feature a ring-shaped bank and ditch, with the ditch inside the bank. Because the internal ditches would have served defensive purposes poorly, henges are not considered to have been defensive constructions. The three henge types are as follows, with the figure in brackets being the approximate diameter of the central flat area:

  1. Henge. The word henge refers to a particular type of earthwork of the Neolithic period, typically consisting of a roughly circular or oval-shaped bank with an internal ditch surrounding a central flat area of more than 20 m (66 ft) in diameter. There is typically little if any evidence of occupation in a henge, although they may contain ritual structures such as stone circles, timber circles and coves. Henge monument is sometimes used as a synonym for henge. Henges sometimes, but by no means always, featured stone or timber circles, and circle henge is sometimes used to describe these structures. The three largest stone circles in Britain are each within a henge. Examples of henges without significant internal monuments are the three henges of Thornborough Henges. Although having given its name to the word henge, Stonehenge is atypical in that the ditch is outside the main earthwork bank.
  2. Hengiform monument. Like an ordinary henge, except the central flat area is between 5 and 20 m (16–66 ft) in diameter, they comprise a modest earthwork with a fairly wide outer bank. The terms Mini henge or Dorchester henge are sometimes used as synonyms for hengiform monument. An example is the Neolithic site at Wormy Hillock Henge.
  3. Henge enclosure. A Neolithic ring earthwork with the ditch inside the bank, with the central flat area having abundant evidence of occupation and usually being more than 300 m (980 ft) in diameter. Some true henges are as large as this, but lack evidence of domestic occupation. Super henge is sometimes used as a synonym for a henge enclosure. However, sometimes Super henge is used to indicate size alone rather than use, e.g. "Marden henge ... is the least understood of the four British 'superhenges' ".

The West Kennet Long Barrow, also known as South Long Barrow, is a chambered long barrow near the village of Avebury in the south-western English county of Wiltshire. Probably constructed in the thirty-seventh century BC, during Britain's Early Neolithic period, today it survives in a partially reconstructed state.

<span class="mw-page-title-main">Causewayed enclosure</span> Prehistoric earthwork

A causewayed enclosure is a type of large prehistoric earthwork common to the early Neolithic in Europe. It is an enclosure marked out by ditches and banks, with a number of causeways crossing the ditches. More than 100 examples are recorded in France and 70 in Southern England and Wales, while further sites are known in Scandinavia, Belgium, Germany, Italy, Ireland and Slovakia.

Combe Hill is a causewayed enclosure, near Eastbourne in East Sussex, on the northern edge of the South Downs. It consists of an inner circuit of ditches and banks, incomplete where it meets a steep slope on its north side, and the remains of an outer circuit. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, meeting places, or ritual sites. The historian Hadrian Allcroft included the site in his 1908 book Earthwork of England, and in 1930 E. Cecil Curwen listed it as a possible Neolithic site in a paper which attempted to provide the first list of all the causewayed enclosures in England.

The Trundle is an Iron Age hillfort on St Roche's Hill about 4 miles (6 km) north of Chichester, West Sussex, England, built on the site of a causewayed enclosure, a form of early Neolithic earthwork found in northwestern Europe. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, meeting places, or ritual sites. Hillforts were built as early as 1000 BC, in the Late Bronze Age, and continued to be built through the Iron Age until shortly before the Roman occupation.

Parc Cwm long cairn, also known as Parc le Breos burial chamber, is a partly restored Neolithic chambered tomb, identified in 1937 as a Severn-Cotswold type of chambered long barrow. The cromlech, a megalithic burial chamber, was built around 5850 years before present (BP), during the early Neolithic. It is about seven 12 miles (12 km) west south–west of Swansea, Wales, in what is now known as Coed y Parc Cwm at Parc le Breos, on the Gower Peninsula.

<span class="mw-page-title-main">Whitehawk Camp</span> Remains of 5500-year-old causewayed enclosure

Whitehawk Camp is the remains of a causewayed enclosure on Whitehawk Hill near Brighton, East Sussex, England. Causewayed enclosures are a form of early Neolithic earthwork that were built in England from shortly before 3700 BC until at least 3500 BC, characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, or meeting places, or ritual sites. The Whitehawk site consists of four roughly concentric circular ditches, with banks of earth along the interior of the ditches evident in some places. There may have been a timber palisade on top of the banks. Outside the outermost circuit there are at least two more ditches, one of which is thought from radiocarbon evidence to date to the Bronze Age, about two thousand years after the earliest dated activity at the site.
