Fossil record, history of life as documented by fossils, the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock.
What is a fossil record?
The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
What best describes the fossil record?
The fossil record is the highly ordered sequence in which fossils are found in layers of sedimentary rock.
What is an example of fossil records?
Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.
What is a fossil easy definition?
Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks. A fossil can preserve an entire organism or just part of one. Bones, shells, feathers, and leaves can all become fossils.
What 4 things do Fossil records show?

This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.
How deep is the fossil record?
The fossil, which was found 2256 metres below the seabed, represents the world’s deepest dinosaur finding.
Which best describes the fossil record the fossil record Cannot?
the fossil record cannot provide evidence of evolution. the fossil record provides evidence of a common ancestor to many species. the fossil record provides evidence that disputes the theory of evolution.
Is the fossil record complete?
The fossil record is incomplete. Of the small proportion of organisms preserved as fossils, only a tiny fraction have been recovered and studied by paleontologists. In some cases the succession of forms over time has been reconstructed in detail. One example is the evolution of the horse.
Which best describes how the fossil record supports the theory of evolution?
Which best describes how the fossil record supports the theory of evolution? The fossil record reveals intermediates that link different species. … The theory of evolution states that all life is related and that organisms have become more complex over time.
How is fossil formed?
Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.

What is the most complete fossil record?
