Sounds very interesting! There is a dust analysis project on the go at 
the University of York, U.K. I think - in December 2010 there was a call 
for dust samples from John Schofield via the email list 
[log in to unmask]; I don't know much more than that but 
it might be a good lead.

From reading previous threads it seems that many people have retrieved artefacts from underfloor spaces and inside walls etc.  I am wondering if anyone has had a chance to look more closely at the actual depositional material or 'dust' itself?

We have retrieved a lot of really fragile material such as paper from newspapers, books, handrolled cigarettes etc that was not preserved in the subsurface deposits we excavated from a ground floor cell (for obvious reasons).   The deposit itself appears to be a mixture of material made up of human detritus such as hair and 'bumfluff' (for want of a more technical term!) as well as other organic material including fibres, insect larvae, rodent skeletons etc

If anyone could point me in the direction of any studies along these lines or has any comments on taphonomic processes in sub-floor contexts it would be much appreciated!
