just a small addition to Jon's very helpful clarification - Jon is certainly
right to consider as 'intrusive' the bones of his category 'c' but in Britain
at least these are more commonly defined as 'residual' to distinguish them from
the 'intrusive' material originating from later layers. I would be interested
to know if a different terminology is used in the North American literature.
Cheers,
Umberto
