I've got a ???just possibly neolithic building which has remained undated cos the specialist ignored all the great lumps of wood-charcoal in the hand-crafted rock-cut postholes and recommended the limited budget be instead spent on some 'short-lived' material which proved too small a sample to date even using AMS....and, err, wouldn't the original posts have pretty much filled the postholes making it a bit tricky for anything else contemporary to have fitted in?...bugger I wasn't in the office to head that one off. Individual cereal grains, or even small groups, are, from experience, to be used only as a last resort, have had some well wacky results (those darned worms!) and hazelnut shell is nigh-on indestructible and hangs around for ever. Give me articulated bone every time.
