The totality of fossilized artifacts and their placement within the rock strata. It provides information about the history of life on earth, for instance what the organisms look like, where and when they live, how they evolved, etc. Second question 1: Only a very small proportion of organisms get buried quickly enough to prevent them decomposing

2: Not all organisms have hard parts

3; Sediments containing fossils are continually being eroded and removed along with their fossil content

4: metamorphism and deformation destroy fossils

5: many fossils are still buried in rocks not exposed at the surface

6: the sea floor in particular is being continuously recycled, so deep marine organisms are seldom preserved.

To become a fossil an organism needs to have hard parts, die and be buried in an anaerobic environment very quickly, and then be preserved through geological time, without being destroyed by tectonism or metamorphism, or removed by erosion. These are pretty rare circumstances, so organisms becoming fossilized are the exceptions rather than the rule.

Fossils are quite rare, as it takes a number of unusual circumstances a) to form a fossil from any given organism (and some organisms don't fossilise at all) b) for the fossil to be preserved and c) for the fossil to be discovered.

Even then, many fossils must have been found by people in the past and then destroyed or discarded. In Ancient China, people believed the dinosaur fossils were the remains of dragons, and used them, ground to powder, as medicines. China today has a lot of dinosaur fossils, but imagine what may have been lost!

As a result, the fossil record that we have probably represents something less than 5% of all the living organisms that have existed on this planet. Many organisms in the fossil record are so far only known through one single example. Finally, the fossil record is heavily slanted towards creatures which have hard, solid body parts, such as vertebrates.

That being the case, the really impressive thing about the fossil record is how much we have, and how many transitional forms are known.

Why will the fossil record always be incomplete?

Because its all a lie. God created us all.


Why is the fossil record unable to provide a full portrait of the times in which the fossilized animals and plants lived?

The fossil record is incomplete because not all organisms fossilize, and not all fossils are found or preserved. Fossilization depends on specific conditions such as rapid burial and mineralization. Therefore, the fossil record only represents a small fraction of the organisms that lived in the past.

The fossil record is incomplete.


What is one reason why the fossil record is incomplete?

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.


Are fossils records complete or incomplete?

Fossil records are not complete. By some estimates, less than 1% of organisms that have lived appear in the fossil record.

Why is the fossil record incomplete?

The fossil record is incomplete because fossilization is a rare process that requires specific conditions to preserve an organism's remains. Factors such as decay, scavenging, and geological processes can also contribute to the gaps in the fossil record. Additionally, not all organisms have hard parts that can fossilize, further limiting the representation of past life.


Do fossil records help to date fossils?

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.
