Structured deposits in the Ditch

Four samples were analysed from animal bones deposited in, or close to, terminals in the Ditch (results). They were placed on the base below the primary silt and so must have been deposited very soon after the Ditch was dug.

However analysis of the results suggests that these objects were collected over a period of 50 and 850 years, between 3900-3050 cal BC and 3020-2910 cal BC. This suggests that the four bones are statistically significantly earlier than the date of the Ditch construction (3020-2910 cal BC), and so may have been curated for a substantial period of time before being placed in the Monument (see probability distributions).
