Why do fossils form better in water?

Water seeps through mud much more slowly than through sand, so the body does not decompose as fast. Mud often contains a lot of other organic matter as well, and that uses up oxygen faster.

Why are land fossils less common than marine fossils?

Marine animals that die near a river delta may be buried by sediment carried by the river. A storm at sea may shift sediment on the ocean floor, covering and helping to preserve skeletal remains. On land, burial is rare, so consequently fossils of land animals and plants are less common than marine fossils.

Why is it easier to find fossils of marine organisms versus land organisms?

A storm at sea may shift sediment on the ocean floor, covering a body and helping to preserve its skeletal remains (Figure below). This fish was quickly buried in sediment to become a fossil. Quick burial is rare on land, so fossils of land animals and plants are less common than marine fossils.

Why do fossils rarely form on land?

Fossils are rare because most remains are consumed or destroyed soon after death. Even if bones are buried, they then must remain buried and be replaced with minerals. If an animal is frozen like the baby mammoth mentioned above, again the animal must remain undisturbed for many years before found.

Why are fossils found near bodies of water?

This is mostly due to the fact that creatures that live in bodies of water have a much greater chance of being covered by sediment and/or transported to low oxygen environments, which increase the chances of it becoming fossilized.

What environment has the best chance of generating fossils terrestrial or marine Why?

Since rapid burial in sediment is important for the formation of fossils, most fossils form in marine environments, where sediments are more likely to accumulate.

Why are you more likely to discover a marine animal’s fossil than a dinosaur fossil?

Nearly all fossils we find – around 99\% – are from marine animals such as shellfish and sharks. This is because they lived in the sea, where sand or mud could bury their remains quickly after they died. But dinosaurs lived on land, so how did they get buried quickly enough for some of them to fossilise?

Why are some fossils more common than others?

Organisms decompose more quickly when they are in contact with oxygen. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.

Are fossils found in the ocean?

Yes! There are sediments on the deep sea floor and sediments can preserve animal hard parts like bones. However, deep sea sediments are not too good at preserving such remains. Teeth are the best things preserved in deep sea sediments.

Where are fossils found and why?

Fossils are usually found in sedimentary rock, which formed near prehistoric rivers. Some are buried deep underground, but others are discovered when wind or rain removes just a thin layer of dirt. Mary Anning discovered many fossils that had been revealed by landslides.

What environment has the best chance of generating fossils?

How did the fossils of marine life rise to their present heights?

Over time that land has uplifted. Thus the fossils of marine life that once lived there have risen to their current high elevations. This is a better answer than a global flood for several reasons: There are also fossilized tracks and burrows of marine life found near the fossils of the marine life.

Why are hard parts of organisms more likely to become fossils?

The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.

How are fossils deposited in the Earth?

Deposition on land is common only in river valleys. Fossils are fairly common in sediments deposited on river floodplains. Some ocean environments that support animal life are exposed to very strong currents and waves. After a shelled animal dies, the strong water motions cause the hard body parts to be broken and worn.
