Which of the following are correct statements about fossils? Correct Answer(s): Fossils are the remains of once-living organisms, wholly or partially transformed into rock. The most common types of mammal fossils are bones and teeth.
Which statement is true about fossils?
Answer: The correct answer would be D) The complexity of the organisms in fossil beds increases closer to the surface. For example, bones, exoskeleton, shells, et cetera.
Which statement about fossils is incorrect?
Explanation: Because only hard organisms have a highest chance to become fossils, like bones, teeth and shells. That’s why is false.
What best describes a fossil?
Which of these answer BEST describes a fossil? fossils are remains or traces of once-living organisms found in layers of rock or ice, or in amber. organism from which other organisms are descended.
What do fossils explain?
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.
How many kinds of fossils are there?
There are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils.
Where are most fossils found?
Fossils are mostly found where sedimentary rocks of the right age – which for dinosaurs is the Mesozoic – are exposed. The best places are river valleys, cliffs and hillsides, and human-made exposures such as quarries and road cuttings.
What is the most common method of fossilization?
The most common method of fossilization is called permineralization, or petrification. After an organism’s soft tissues decay in sediment, the hard parts — particularly the bones — are left behind.
Is fossilization a common occurrence?
Fossilization is a fairly common occurrence. … There is virtually no fossil record of organisms that lacked hard parts such as bones or shells. _____ 5. A dead organism is less likely to become a fossil if it is buried by sediments.
Why are homologous structures used as evidence for evolution?
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness.
What are 4 types of trace fossils?
Examples of trace fossils are tracks, trails, burrows, borings, gnawings, eggs, nests, gizzard stones, and dung. In contrast, a body fossil is direct evidence of ancient life that involves some body part of the organism.
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.
What’s the definition of index fossil?
Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
What are the 7 types of fossils?
What are the Different Types of Fossils
- Body fossils – Soft parts. The first type, body fossils, are the fossilized remains of an animal or plant, like bones, shells, and leaves. …
- Molecular Fossils. …
- Trace Fossils. …
- Carbon Fossils. …
What are some examples of fossils?
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 importance of fossils?
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
