Fossils, tracks, and burrow marks indicate specific life forms and climate conditions, as well as pinpoint the age of the rock.Sedimentary structures, like those in Figure 7-2, are commonly preserved in sediment (e.g., ripple marks, mud cracks, etc.). Sedimentary rocks can form from loose sediment of various sizes (i.e., mud, sand, gravel), from mineral crystals (like silica or calcite) that evaporate or precipitate from water, or from the accumulation of organic material. In the latter case, geologists must find primary features of the rocks, such as ripple marks or crossbeds, that preserve evidence of which way used to be up. Figure 1.
