Around 239 excavated burial sites have been identified in the study area dating to between AD 300 and AD 800. These include approximately 4060 separate funeral events.
Acid soils across Northumberland mean that bone survival is poor but 49 of the sites (20%) have bone or fragments.
These include Catterick, Norton, and Ripon in North Yprkshire, Sewerby and Kemp Howe in East Yorkshire, Seaham in Co. Durham, and East Linton, Dunbar, and Carmmond in the Lothians.
Cemeteries that have recently been analysed include West Heslerton inYorkshire, and Bamburgh in Northumberland.
The north and west of the study region present challenges but bone survival at locations such as Binchester in Co Durham, The Dog Hole in Lancashire, and Heronbridge in Cheshire offer additional possibilities for dating and sampling.
