Full Answer

The body of an insect is divided into the head, the thorax and the abdomen. The head contains the insect's mouth parts, eyes and antennae. The thorax holds the legs and the muscles used in locomotion. The abdomen holds the digestive and reproductive organs.

The exoskeleton is made out of a tough material made of chitin. To grow, the insect must shed this exoskeleton or moult from time to time.

    What makes a good index fossil?

    A:

    The qualities of a good index fossil are that it belongs to a relatively abundant and widely dispersed species that nevertheless existed for only a brief time on Earth. Marine animals best suit these parameters as sea currents carry them to distant shores where the tide gradually layers upon them the sediments that later form solid, sedimentary rock. The most common index fossils are the pre-historic mollusks called ammonites.
