I've had a break from soil processing lately, as I was roped in to finish sorting some processed soil samples where we had an upcoming deadline. It is a great site, the old kitchen backyard from an Oxford college, and I can't wait to get my hands on the bones and do the analysis. The samples were full of fish bones and foot bones from rabbits (presumably the rest of the rabbit was discarded elsewhere with the food leftovers), as well as other bits and bobs. But oh how my eyes were tired. I had to give up my usual embroidery hour in front of the tv every single evening after doing the sorting of the 10-4mm and 4-2mm fractions.

Imagine one stack of A4 papers for the printer. Fill a tray of that volume with small gravel, charcoal and bone, all from the 4-2mm sieve. Carefully tip out what you can get with one hand stroke on to a shallow tray. Sort it and discard the leftovers. Repeat 6-7 times (or more) until the big tray is empty.

One such shallow tray before sorting.

What I got from an entire 4-2mm tray. Mammal and bird bones to the left and fish bones to the right. Thankfully we ignore the charcoal from this sieve size.
