Most fossils "hide out" in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Clastic Sedimentary Rocks . The most common set of sedimentary rocks consists of the granular materials that occur in sediment. Sediment mostly consists of surface minerals — quartz and clays — that are made by the physical breakdown and chemical alteration of rocks. These are carried away by water or the wind and laid down in a different place.

In this lab, we will look at three types of clastic rocks (Figure 10.1, Table 10.1), conglomerate, sandstone, and shale. Conglomerate is an immature sedimentary rock (rock that has been transported a short distance) that is a poorly sorted mixture of clay, sand, and rounded pebbles. The mineralogy of the sand and pebbles (also called clasts ...
