Not all organisms became fossils. In fact, for an animal or plant to fossilize is a rare occurrence.
Most fossils are found in sedimentary rocks which formed at the bottom of seas or oceans, but no present oceanic crust is more than 200 million years old.
Only relatively small areas of oceanic sedimentary rock were preserved on land due to the actions of plate tectonics, the rest were part of shallow continental seas, drowned areas of land similar to the South China Sea or North Sea today.
Nowhere on Earth has a complete, unbroken sequence of rocks from earliest times as our planet is constantly moving, new oceans being born and mountain ranges being formed. So you cannot have an unbroken record of fossils from the beginning of life, although more new finds are being discovered every year.
1. Fossils show that life did not always have the forms that it has now. It shows that significantly different lifeforms existed in the past, and now no longer exist.
2. Fossils show that life in the past has progressed in a series of forms that each seem remarkably similar to both earlier and later forms, indicating that heredity is a factor in their emergence.
3. Fossils show that the life that existed in the past adhered to the same set of nested hierarchies as life today, and that, as time progresses, the forms in these hierarchies of fossils approach the forms in extant life.
These three observations confirm the existence of evolution in general and common descent in particular.
There are missing links. However, the fossil record supplies fantastic evidence for the theory of evolution.
it depends on what the fossil is about. like dinosaurs : they have fossils because of the plants that took shape
Fossils of dinosaurs are often incomplete because parts of the bones may get crushsed or destroyed or seperated from the other bones and just haven't been found yet
The fossil record is incomplete because not all fossils have been discovered. In actuality it is unlikely that all fossils will ever be discovered given the hit and miss nature of fossil discovery which usually occurs through educated guess work. The fossil record will likely never be complete.
They think it has too many gaps in it to explain anything, even though biologist have proven many, many things with fossils.
The way fossils are formed in very dry places is called mummification. Amber is a hardened tree sap, yellow to brown in color, and often a source of insect fossils.
There are so many well preserved fossils because there are so many fossils, some will be well preserved. In certain locations at certain times the conditions will be right for preserving living tissues.
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.

Paleontologists are looking for fossils in sedimentary rock.
not that often
True
yes
fossils
They Often Contain fossils.
sedimentary
They Often Contain fossils.
Most often it is a paleontologist who finds dinosaur fossils. However, anyone can find one.
Fossil records are not complete. By some estimates, less than 1% of organisms that have lived appear in the fossil record.
Fossils. I'm just guessing but that sounds right. I have it for homework, and im doing it right now
