Fossilised ripple marks. Cyclic and rhythmic aeolian stratification in a slab of sandstone. Small-scale, fossil ripple structures in a slab of sandstone. Here the ripple marks stand out clearly due to the varying grain size and the iron content of the very thin, wind-deposited layers. Specimen from the Jurassic Navajo formation, southern Utah state, USA.
