How do most fossils form? Be sure to explain your answer.
OlgaM077 [116]

Answer and Explanation:

Fossils can be formed in a variety of ways. First and foremost, organisms that possess bones (or shells) are the best candidates for fossilization because these structures commonly remain in fossilizing substances such as mud.

The most preserved fossils come from animals that die in aquatic environments or in environments that have a high level of humidity. This occurs because the animal gets buried in a sediment like mud, leading to the decomposition of soft structures and the fossilization of hard structures, such as bones. As layers of sediment are added, the dead body of the organism becomes a fossil.

Also, animals can leave well-preserved fossils during volcanic eruptions when they get trapped in hot ash flows. In addition, this could also occur in tundra ecosystems when animals get trapped in ice, leaving a well-preserved fossil inside. Moreover, plants are also fossilized, this generally takes place in sediments such as coal.

Finally, paleontologists are able to find the fossils once they become exposed thanks to a process called erosion.

During the end Permian mass extinction, the die-offs were so extensive, __________ or more of animal species went extinct.
Lana71 [14]

During the Permian mass extinction more than 80% of the global animal species went extinct.

<h3>What was the Permian mass extinction? </h3>

This was one of the many mass extinction events that occurred during the Earth's history. Mass extinction events are global die-off's of animal species. Throughout history, these have been caused by many factors, but often include a sharp change in global weather conditions. The Permian mass extinction killed of 95% of all land species and 70% of all marine life, averaging around 80% in total species.

Therefore, we can confirm that during the Permian mass extinction more than 80% of the global animal species went extinct.
