<span>Fossil records are described as the position of found fossils all
through the surface or the layers of the earth. The older the fossils are, the
deeper it is found. Fossil records are also considered to be gathered
information about the total number of the discovered fossils and the data obtained
from them. Fossil records are important guides to determine how life existed
before. If you are to assemble a fossil, you will be able to see and tell the
evolutionary changes that happened over the past years. Fossil records are evidences
pointing out that life before is totally different from now. </span>
fossil record, history of life as documented by fossils, the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock.
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind.
Shape of Red Blood Cells Erythrocytes are biconcave discs with very shallow centers. This shape optimizes the ratio of surface area to volume, facilitating gas exchange. It also enables them to fold up as they move through narrow blood vessels.
