Why Is Body Fossils Important

There are a lot of misconceptions while talking about fossils. Fossils are not limited to the remains of a once living thing, but rather the evidence of life that existed in the past. This means that a fossil can be a dinosaur footprint, the form of a body on dry mud, bones, etc.

We use fossils to compare and contrast how and organism has evolved over a long period of time and how it has adapted to new changes.

Fossils grant us opportunity of understanding about species which no longer exist on Earth- that are extinct. The prehistoric remains inform us about plants and

In the following space, explain the role of fossils in developing the Geologic column. Your explanation must be between 200 and 300 words.

Paleontology or paleobiology is the study of plant, animal, and microorganism fossils found on the earth. Paleobotany focuses on algae, fungi, mosses, ferns, seed plants

From both the title of the chapter and the introduction by Dr. Shubin, this chapter begins with a focus on teeth. Because the function of teeth is to break down food before it enters the esophagus, the different shapes of teeth can represent many different things about the organism it belongs to including what type of eater it was (carnivore, herbivore, or omnivore). Teeth are the hardest tissue (not bone) in the human body and therefore fossilize well. As Dr. Shubin stated in chapter one, there must be many points that permit a fossil to make any kind of scientific conclusion. Obviously, the state of their presence is important, so the fact that teeth preserve well allows for them to be great specimens for analysis. Dr. Shubin and his team analyzed fossilized teeth in areas as different as Nova Scotia and the Arizona desert. Studying different fossils in these diverse regions allowed the team to see that mammalian and reptilian teeth are very different. For example, mammalian teeth differ from organism to organism to fit with the organisms need (Cheetahs that eat only meat will have different teeth than deer who are herbivores) and are replaced only once in the lifetime of the organism while reptilian teeth are usually sharp and are constantly replaced if damaged. These differences allowed scientists to characterize fossils as either a reptile or a mammal. Similar to Tiktaalik discussed in chapter one, the discovery of fossils that were part reptile and part mammal allowed the researchers to see that mammals evolved from reptiles, and further supported the theory of evolution. Further studies yielded even more

Fossil discoveries are extremely significant to science and they help people better comprehend the world they live in. Without these discoveries science wouldn’t of grown like it has and people would not know much about the Earth. The fishapod and the dinomummy are two fossil discoveries that have made a gigantic impact on science. The fishapod helped fill the gap between land animals and water animals and the dinomummy proved that dinosaurs vertebrae are different than scientists have been placing them. However, the most important part is the preservation of these two ancient creatures. If they hadn’t of been preserved like they had, then they would never of been discovered and scientists wouldn’t get to learn from the remains of these creatures.

This is a great way to think. Everyone has their skeletons; no one is perfect. Some individuals have done worse than others, of course, but the worst of them also have qualities that really make them stand out. To me, thinking of one’s positive qualities really helps to not be so judgmental on the negative qualities. It’s interesting because when I look back on the memoir, this quote reminds me of how Jeannette looked at her dad. He was an alcoholic, he would take their money just to buy cigarettes and alcohol, and did let her and her siblings down a lot. However, she always seemed to look up to him because he was this person that always thought outside the box. In the book, we see how much he believes in her, and how he, for the most part,

It is important because it was almost a missing link to evolution. Therefore, it could have falsified evolution. The kind of rock’s we’re very old which was the best place to look for the fossil that was also very old.

Second, the author thinks that business in selling the fossils, reduce the access of scientists to these fossils as a great source of scientific evidence, but the professor explains that all fossils need scientific evaluation by scientists for price marking, so all fossils are

Because dinosaurs are animals that lived millions of years ago, we are entirely dependent on the fossils that they have left behind for any understanding that we hope to gain. As any paleontologist will tell you, fossil hunting is difficult. There are no certainties, no guarantees. A certain amount of luck is as valuable as any scientific knowledge.

The fossil record is evidence of evolution. Fossils are often fingerprints of evolution. They help scientists track how species evolved

: Fossils are the remains or traces of ancient organisms which have been preserved. For example, a fossil can exist as skeletal remains or even as a footprint. Such organisms are subjected to a slow rate of decaying since they have been rapidly buried under conditions that facilitate this. It is common for fossils to occur as hard-bodied organisms as these are more resistant to environmental influences. Fossils are usually found embedded in rock. The layers of rock are of different age and makeup. Hence fossils found in one layer would vary in characteristics from those found in another layer. They can be observed and analyzed through visual as well as radiometric means so that the age and morphology can be determined. These features indicate

Understanding fossils can provide insight into so much more than what lived millions of years ago. From my reading there seem to be 4 major categories that fossils can help us with. Fossils and fossilization, fossils and living organisms, fossils and evolution, fossils and stratigraphy. Understanding fossils helps us understand life and the conditions that supported life millions of years ago. There are two different types of fossils. Body fossils and trace fossils. Body fossils are actual remains of plants and animals while trace fossils are they evidence they existed, things like there tracks, burrows, etc. When these fossils are used together they help scientist learn about a mode of life. Understanding how fossils are formed also helps

Fossils tell the story of the Earth, and the organisms that lived before us. Fossils are the preserved remains of once living organisms (Stanford 222). Some are hard parts such as bones and teeth, others are trace fossils, such as burrows or trails, and lastly there are natural casts, such as molds and impressions (Breithaupt). Fossils are preserved by being buried under
