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.
What else can I help you with?
Why is the fossil record unable to provide a full portrait of the times in which the fossilized animals and plants live?
The fossil record is incomplete.
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.
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.
Why will the fossil record always be incomplete?
Because its all a lie. God created us all.
Explain why the fossil record contains an incomplete record of the history of life on Earth.?
The fossil record is incomplete due to the biased preservation of certain organisms, as only a small fraction of all organisms that have lived on Earth become fossils. Factors like rapid decay, destruction of fossils by geological processes, and limited fossilization conditions also contribute to the incomplete nature of the record. Additionally, the fossil record is further obscured by gaps in sediment deposition and difficulties in accessing and excavating fossils from certain areas.
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.
What is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D
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.
What was first animal born in water?
The first animal life on Earth was in the ocean in the Precambrian time. The exact nature of the first animals is not known as the fossil record from that time is incomplete.
What is the Sepkoski Diversity Curves?
The tendency of loss at extinction boundaries to appear, because of incomplete sampling, more gradual in the fossil record than it actually was during the extinction event.
What is Non-evolutionary Trends?
-The tendency of loss at extinction boundaries to appear, because of incomplete sampling, more gradual in the fossil record than it actually was during the extinction event.
