- Context
- peat overlying till, close to the site of GSC-6495 (shell)
- Additional information
- The tree would have grown when sea level was 1.5m lower than present.
- Comments
- Comment (J. Shaw): The wood was in growth position, and was embedded in 20 cm of peat overlying till, together with other tree and shrub remains. This indicates a freshwater to brackish environment behind a barrier attached to Cape Antrim, at a period when relative sea level was approximately 1.5 m lower than today. Thus, the tree grew just above the former high tide level. The barrier has migrated landwards, exposing the peat and wood on the foreshore.
