Fossils

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

The first chapter of the book discusses the way we can use fossil records to study the biological world. Fossils are one of the major lines of evidence we use to understand ourselves. Surprisingly, we are able to discover them with a high amount of precision and predictability. In particular, field paleontologists have it easier than it has ever been before due to the current information age. The physical hunt for important fossils, however, is much like it has always been. Three factors limiting the number of useful fossil sites include rock age, type (whether or not it can preserve fossils), and number of exposed rocks. So, it takes a bit of luck to reliably find fossils. Thankfully, rock

Layers of soil are laid down on dead animals or plants embalming them. The minerals replace the organic matter creating the fossil.

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.

Fossilization is the process where bones evolve into fossils and preserve in different environments that help to sustain ossein. Some environments include permafrost, amber, peat, dry air, or within sedimentary rocks. There are several different ways that fossils can be classified; this includes original, replacement, carbon film, and indirect fossils. ‘Original fossils for when part of the organism is preserved, with chemical composition being about the same as it was when it was living’ (Pearson Science, 2018). ‘A replacement fossil forms when a part of the organism is chemically changed into another mineral. Replacement fossils commonly form when the calcium carbonate found in shells and bony skeletons turn into another mineral such as silica, also called silicon dioxide’ (Pearson Science,

(B) - The recognizable remains of a plant or animal are known as fossils. Unlike artifacts, fossils are not made by man and instead come from living things. Those who study fossils are known as paleontologists. The word “fossil” comes from the Latin word “fossilis”, which means “found by digging”.

Paleontology is associated with geology. Paleontology is the result of the development of the Geologic Time Scale. There are many feature that deals with the period of Geologic Time Scale.

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

The fossils in the lower silty layers were most likely formed below water by normal geological processes. The sea level rose covering the organisms and the layers of silt settled above them. In the upper sandy layers the fossils could have been formed above water by a sudden catastrophic event as a result of ongoing erosive processes. The conditions in which the fossils formed were likely a result of wave action which eroded the coast line until it was unstable. When the sea level receded there was a landslide covering the

The author and his colleagues chose to focus on 375 million year old rocks in their search for fossils because amphibians that look dissimilar to fish were discovered in 365 million year old rocks, while fish without amphibian characteristics were discovered in 385 million year old rocks. Thus, it is possible that the evolutionary intermediary, or the “missing link” between fish and amphibians, would be discovered in 375 million year old rocks, between the two time periods. The rocks examined were sedimentary in composition, as the gradual and relatively gentle formation of sedimentary rock under conditions of mild pressure and low heat are conducive to the fossilization of animal remains. Sedimentary rock is also often formed in rivers and seas, where animals are likely to live. This site provides a resource that describes means by which fossils are formed and how the fossil record may be interpreted, and shows some examples of fossils demonstrating evolution through geological periods: http://www.fossilmuseum.net/fossilrecord.htm. In 2004, Shubin and his colleagues were looking for fossils on Ellesmere Island, in northern Canada. This location was chosen because of its lack of human development, as well as of obstructing natural formations and life forms such as trees, which

Fossils are preserved by the mold and cast, trace fossil, and carbonization. Sap of a tree and amber preserve fossils by casting a hard stone-like coating on the

Fossils are organisms that were once living but have now died and been preserved in sediment. Their bones can remains can tell how they lived, what they ate, and what their behavior was like. In the article titles, “Fossils: How Are They Made?”, it states that, “The remains inside the rock also turn to rock. The remains are replaced by minerals. The remains literally turn to stone.” There are also other ways an organism can be fossilized, such as being buried in tar. For example, in the La Brea Tar Pit in the city of Los Angeles, they found remains of many ancient beings such as wooly mammoths and sabertooth tigers. In the video “Death By Tar Pit” on discovery.com, it was stated that remains of over 3 million ice age fossils were found in there because they had died and their remains were preserved in the tar pit. An organism can also be fossilized by being trapped in tree sap which
