> The packed sediments were then transported to the laboratory for further sorting. A program of sediment sorting, that lasted over two decades, included the separation of different types of categories: ostracods, mollusks, reptiles, amphibians, micromammals, fish and macrobotanical remains, in addition to different types of small rocks.

Incredible. They didn’t find intact hunks of charcoal (obviously), but instead they _sorted through sediment_ to find grains which they then identified under a microscope.

Archaeology is such a cool field.
