A handbook for new diggers?

[Dinosaur]

I remember an environmental archaeologist wearily describing how someone brought him several buckets of soil, when what he needed was a sample the size of a matchbox from a very specific location. Plus a site post-ex plan which had specified a one litre soil sample from each context

Am impressed by specialists who can reconstruct past environment, diet etc from only 1 fishbone and a couple of charred seeds, must save loads of money, although of course they're shooting themselves in the foot commercially, the usual mantra in evaluation reports is "this looks interesting, process the other 30L of the sample and then I'll do some really expensive analysis" }
