Question

Scientists who study the rocks , minerals , landforms and the history of the earth can tell

what kind of plants and animals lived on the earth a long time ago. These scientists are

called geologists. One way that they are able to do this is by the study of fossils. Fossils

may be the actual remains of plants or animals, impressions of them in rock, or the track

of animals as they walked or crawled.

Most fossils are formed in the waters covering the continental shelves, in warm,

shallow, inland seas, and in large swamps that covered large parts of the land in post

geologic time. When the animals of these waters die, their remains are deposited on the

floor of the water body where the fleshy part of the animal decays. The skeletal portion

of the body is partially replaced by minerals and other sediments. If this takes place in

just the right manner, a fossil is formed. Since rock sediments are involved in the

formation of fossils, it is not surprising that one finds many fossils in sedimentary rock

layers. Plant fossils are found in the areas that where once swamps. There are four

principle kinds of fossils: original remains, replaced remains, moulds and casts, and

impressions.
