Hollow place in rock made when an organism died and was buried and holes in the rock let air or water reach it and dissolve the organism

When this happens it creates a mold because it is a cavity left behind in the rock.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
