Common Phases
Fossil fuels: Coal, oil and natural gas are known as fossil fuels because they were formed from the fossilized remains of ancient plants and animals.
Fossil record: The preserved remains of ancient life found embedded in rock layers, providing evidence about the history of life on Earth.
Living fossil: Certain organisms that have survived relatively unchanged for many millions of years are called living
fossils.
End fossil: A fossil that indicates the last time a particular species was known to exist.
Index fossil: A once-common fossil that lived for a short time period, used to correlate rock layers and determine their relative ages.
Trace fossil: Fossil evidence of the activities or markings of ancient organisms, rather than the remains of the organisms themselves.
Petrified fossil: A fossil in which the organic material has been replaced by minerals while retaining the original structure and shape.
The fossil record is incomplete: Only a small fraction of organisms that have lived on Earth are preserved as
fossils, providing an imperfect view of evolution.
Fossils provide evidence of evolution: The fossil record contains evidence of how organisms have changed progressively over time, supporting the theory of evolution.
Fossils are used to date rock layers: The sequence and types of
fossils embedded in rock layers can be used to determine the relative ages of the rocks.
