| Most types of common marine fossils, buried in shale, limestone, and sandstone and initially laid down in prehistoric seas, are found in coastal areas where the sea is actively eroding cliffs. Many of the hard-shelled invertebrates and early vertebrate animals are fairly well represented in the fossil record, while soft-bodied animals, such as sea anemones and worms, are poorly represented. | ||||||
