The image shows a box filled with rocks on top of a table, with a paper and a scale beside it. The box is filled with a variety of rocks, some of which appear to be brachiopod, a type of shell found in the Mediterranean Sea. The paper has a barcode printed on it, and the scale is likely used to measure the size of the rocks.
