The single most characteristic feature of sedimentary rocks is stratification, the arrangement of visible layers.
The oldest layers of sedimentary rock are always on the bottom of a column. The youngest layers are always on the top of a column.
Some sedimentary rocks contain fossils. These could be the remains, impression, or any other evidence of a plant or animal preserved in rock. See Chapter 29 for details.
