Palaeontologists, people who study fossils, divide them into two major types – body fossils and trace fossils. Body fossils show us what a plant or animal looked like. The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves.

What are the Different Types of Fossils
|Mold fossils||A fossilized impression made in the substrate; a negative image of the organism.|
|Trace fossils or Ichnofossils||Fossilized nests, gastroliths, burrows, footprints, etc.|
|True form fossils||Fossils of the actual animal or animal part.|
What are the two 2 correct example of trace fossils?
Trace fossils record the activities of organisms. Tracks, burrows, eggshells, nests, tooth marks, gastroliths (gizzard stones), and coprolites (fossil feces) are examples of trace fossils or ichnofossils.
What are the 5 main types of fossils?

What are the 3 main types of fossils?
Scientists categorize fossils into three main groups – impression fossils, trace fossils, and replacement fossils. Amber is also often looked at as a fourth type of fossil. Although a chunk of amber can contain insects that were trapped in resin long ago, technically it is still categorized as a gemstone.

How are fossils classified?
Trace fossils are classified in various ways for different purposes. Traces can be classified taxonomically (by morphology), ethologically (by behavior), and toponomically, that is, according to their relationship to the surrounding sedimentary layers.
What are fossils very short answer?
Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks. A fossil can preserve an entire organism or just part of one.
What is a fossil footprint called?
A fossil track or ichnite (Greek “ιχνιον” (ichnion) – a track, trace or footstep) is a fossilized footprint. … Over the years, many ichnites have been found, around the world, giving important clues about the behaviour (and foot structure and stride) of the animals that made them.
What is carbonization of fossils?
Carbonized fossil remains (also called carbonizations) may result when organisms are rapidly buried, especially in low-oxygen conditions. Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock.
What can we learn from trace fossils?
Sometimes, tracks and fossils do tell us something about the organism, for example, dinosaur footprints. Examining the footprints left behind by dinosaurs give us a hint as to the size of the dinosaur. Most of the time there is a certain proportionality between an organism’s body and its legs (feet.)
