Agrichnia: farming traces. Constructed by animals that grow algae or trap food particles.Pictured above is sandstone displaying classic herringbone cross-beds. Cross-bedding results from either sediment transport by flowing water, such as in this example, or by wind flow, as in the case of dunes. Cross-beds form by the migration of sediment, and tilt in the direction of flow. As sediment grains are carried by the current, they ...Asthenosphere.
