An index fossil is a fossil that is found in only in layers of rock of a particular geologic age such as a shell found in a rock. mold fossils (a fossilized impression made in the substrate - a negative image of the organism) cast fossils (formed when a mold is filled in) trace fossils = ichnofossils (fossilized nests, gastroliths, burrows, footprints, etc.) The process of fossilization - 3. Were students able to identify each fossil? There are slight differences in each. The structure of the animal or plant remains as a mineral form. The irregular urchins use their tube feet for digging their burrows and maintaining them. When the imprint hardens, it forms a fossil in the shape of the original. The limited life-spans of these organisms allows us to easily constrain the age of rocks in which they occur. An artifact can be described as an object made by humans and also it is a work of art. Fossils come in two forms: Body fossils and trace fossils. Impression fossils form when a leaf, shell, skin, or foot. We can find leaves or wood in fossil form.

Trails are fossilized structures created by ancient animals moving around on soft material. So, if you were to draw a comparison of the two, mold fossils take up all the negative space in an organism while cast fossils hold all the positive space. Both artifact and fossil can be defined as the interests of archaeological studies. Plants uptake atmospheric CO 2 during photosynthesis through the 'leaf stomata'.
