The reason for this is because a sedimentary rock is mainly because it is the only rock that would be able to keep the fossils form. If a fossil was to be in a metamorphic rock in would be deformed because i metamorphic rock needs pressure which would then flatten the fossil. If it was to be in an igneous rock the fossil would melt because an igneous rock is created from hot lava from

Fossils are the remains of either a plant or animal that lived in prehistoric times, the fossil is usually found preserved into rock. Fossils show us the steps of evolution that life has taken until today. When we trace fossil records back we can start to understand how species have progressed and what they appeared to look like. We can then compare (if the species still exists) what changes they have undertaken by using the fossils as a source. From that proof we can also compare the prehistoric biota with modern day biota and consider possible relatives. As well as being a window to the past, the remains of flora and fauna let us predict how Australian biota may evolve in future.

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

Sedimentary rocks interpret dinosaur habitats through encased environmental structures of the past. Through sedimentary rocks, paleoecologists’ can examine the arranged formation of sedimentary structures to specify what type of environment the dinosaurs’ lived in. An example of a specific sedimentary rock structure can be seen through formed weathering and ripple marks by how wind and sand formed distinct patterns in the past layered sediment. These arrangements provide interpretations on the structure of the sediment and the habitat of encased fossils, through modern day comparisons

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

They chose the time period of 375 million year old rocks because they thought that it was an ideal age to check the transition. They were only able to find fish found in 380 million year old rock and the animals with limbs in 365 million year old rocks. Sedimentary rocks are ideal because they are made due to the turns of the river, ocean and lakes. This is the place where fishes and animals are ideal to live and survive upon. Also the environment, in which they are made, doesn’t destroy the fossils and they preserve them. In 2004, the fossils were found on Ellesmere Island in Northern Canada. This location was chosen because this is the place where there are no humans or roads or any disturbance that would forbid them to dig anywhere they want.

At the time, although it was understood that fossils were the hardened remains of dead animals, it was not yet accepted that these animals might be extinct species from hundreds of millions of years ago. So, when Anning showed up with a giant marine reptile fossil (the world’s first Ichthyosaur) it caused quite a stir, because at the time the Bible was widely used for interpreting scientific ideas and religion ruled people’s lives. Hence Anning’s findings encouraged the largely creationist population, to rethink the history of the Earth. Her fossils had helped scientists understand how things

Molds can be found roughly everywhere on the planet as long as the two most basic life requirements are available, moisture and oxygen. When too much moisture is available mold growth will take place, especially if the moisture is not controlled. Eliminating all molds and mold spores is nearly impossible, but it can be controlled and is supported by the Clean Air Act.

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

According to the US EPA from their on-line course (http://www.epa.gov/mold/moldcourse/index.html), molds are organisms that may be found indoors and outdoors. They are part of the natural environment and play an important role in the environment by breaking down and digesting organic material, such as dead leaves. Also called fungi or mildew, molds are neither plants nor animals; they are part of the kingdom Fungi.

: 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

My outside source for questions 3 and 4 is a journal by Pat Shipman titled Fossils. This journal was published in The New Scientist Vol. 215, Issue 2876, p. 8-16.

These techniques led to the discovery of the boundary between the two eras. A single thin layer of clay found within predominantly limestone rocks established this. By comparing the marine life found in, above, and below the clay, the marine life, like the dinosaurs, had been terribly affected by the extinction event. The percentage of life in the upper layers was dramatically lower than that in the lower. This was far more compelling than what was suggested by dinosaur’s fossils.

One of the early methods of glass making was called core forming. This technique made use of a metal rod that had clay attached at one end. The end of the rod with the clay around it was either lowered into molten glass or the glass was poured onto the clay. The glass surrounding the clay would solidify
