- Any layer of rock in a sedimentary sequence that can be distinguished from the layers above and below is a bedding plane. Bedding planes, also called beds or strata (singular: stratum) are the simplest sedimentary structures and the smaller lithostratigraphic unit used by geologists to describe sedimentary formations.geologyistheway.com/sedimentary/bedding-and-lamination/
