What are animal fossils?
Fossils are the remains of prehistoric life, especially those preserved in rock before the end of the last ice age. A fossil might be the animal or plant itself, or the bones or shells of animals (sometimes altered), or the imprint of a plant or animal (for example the mold or cast of a shell).
Which animals form fossils?
By far the most common fossil remains are those of shelled invertebrate aquatic creatures such as snails, corals, and clams. Fossils of terrestrial (land) animals are scarcer than those of plants. In order to become fossilised, animals must die in a watery environment and become buried in the mud and silt.
What are fossils give examples?
Fossils are the remains or traces of ancient life that have been preserved by natural processes. Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber, petrified wood, coal, hair, oil, and DNA remnants.
Are fossils rare?
Fossils are rare because their formation and discovery depend on chains of ecological and geological events that occur over deep time. As such, finding fossils involves not only perseverance and luck, but the discovery of any particular fossil also depends on the chance that the specimen preserved in the first place.
What are the 4 types of fossils?
There are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils.

Is a shell a fossil?
The most common fossils are shells of marine animals like clams, snails, or corals. The insect fossil is preserved in the amber, often perfectly. Sometimes the actual shell or bone is preserved.
What are 2 types of fossils?
There are two types of fossils- the body fossils and the trace fossils. Body fossils include preserved remains of an organism (i.e. freezing, drying, petrification, permineralization, bacteria and algea).

What is a dinosaur fossil called?
This may be their preserved remains or other traces, such as marks they made in the ground while they were alive. Fossilised remains – including fossil bones and teeth – are known as body fossils. Fossilised shells are also body fossils.
