Why is it important for scientists to study fossils?
Fossils are traces of ancient life. Scientists use fossils to gather information about the lives and evolutionary relationships of organisms, for understanding geological change and even for locating fossil fuel reserves.
What can scientists learn by studying fossils I how the Earth’s surface has changed over time ii the appearance of an organism and its structures III how species have changed over time IV how the Earth’s climate has changed over time?
By analyzing the remains of fossilized organisms (such as old animal bones or plants), scientists can approximate what the organism might have looked like and the climate/environment it lived in — and based on that, they can try to figure out how the Earth’s surface has changed over time.
What can Fossils teach us?
By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
What are three types of fossils?
This week’s homeschool science corner is all about the three main types of fossils. Scientists categorize fossils into three main groups – impression fossils, trace fossils, and replacement fossils. Amber is also often looked at as a fourth type of fossil.
Why are fossils useful?
Fossils are physical evidence of preexisting organisms, either plant or animal. Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited.
Are fossils rare?
Fossils are rare because most remains are consumed or destroyed soon after death. Even if bones are buried, they then must remain buried and be replaced with minerals. Here’s a good link with extensive information about fossils, the different types, the processes that preserve soft body parts, and more
Can a human become a fossil?
Birds, for example, are very, very rare in the fossil record, because avian bones are incredibly fragile, and are unlikely to remain intact long enough to become fossils. On the other hand, it turns out humans are actually fairly well-suited to becoming fossils. Most of the fossils we find of mammals are teeth.” Great!2015年5月1日

What is the most expensive fossil in the world?
A video on the T-Rex fossil that was recently sold for record breaking $31.8 million. The fossil, nicknamed Stan, is one of the most complete specimens of a T-Rex fossil in the world. It was recently sold for a record $31.8 million by Christie’s in New York.
Is it illegal to sell fossils?
Fossil trading is the practice of buying and selling fossils. This is illegal when it comes to stolen fossils, and some important scientific specimens are sold to collectors, rather than given or obtained by museums and institutes of study. The trade is lucrative, and many celebrities collect fossils.
Can you keep fossils you find?
No other country allows hunters to keep whatever dinosaur bones and teeth (or other fossils) they find on their own property, or on land where they have permission to collect. Public lands are off limits—it’s illegal to collect most fossils on federal property, such as the national parks.
