Integrating an evidence based decision support system for in situ preservation of waterlogged organic archaeological remains
Fading Star - Shining Light is a project based at the University of York aimed at ensuring that scientific advances in the knowledge of how organic archaeological materials deteriorate in waterlogged contexts are effectively incorporated into working practices.
Across the UK and Europe, a policy of leaving an archaeological site in situ (un-excavated) is widely pursued. However, a number of recent research projects, including a NERC funded project at the Mesolithic site of Star Carr, indicates that this policy is not always advisable, as changing environmental conditions may in fact accelerate the decay of organic remains such as bone and wood.
These case studies have shown us that before a site is left in situ we need to have a thorough understanding of:
Artefacts recently excavated from Star Carr (right) were alarmingly deteriorated when compared to those excavated in during the first excavations at the site in 1948 (left). Research has shown that this is due to loss of waterlogging at the site
