Fossilized ripples are sedimentary deposits shaped by currents, which later hardened into rocks, preserving the ripple marks. Found mostly around Mudawwara in southern Jordan, they were formed over 450 million years ago when silty deposits hardened into laminate rocks. The ripple marks are high relative to their wavelength, which indicates they were formed by water, not wind. They are symmetrical, which indicates they were formed by shallow waves, not strong currents.
