1. What information do fossils provide about past life on Earth? What information do fossils not provide?…
First of all the scientists I have chosen is a man named Nizar Ibrahim who is a Paleontologist. To begin Nizar Ibrahim is a German/Moroccan Paleontologist who searches the North African deserts to find clues about the life in the Cretaceous period. When the area he is exploring was a large river system it supposedly had a very diverse amount of dinosaur life in it including a new species of flying reptile that had a 18 foot wingspan and lived in this area 95 million years ago. Also in his upcoming paper he is describing the ecosystem of the Morocco's Sahara Desert and how it looked in the mid-Cretaceous period. He is also explaining how his findings are great because…
The coastline I have chosen is part of the world heritage site (the Jurassic Coast), from Old Harry Rocks to St Oswald's Bay…
The discovery of the Comb jelly which was the first animal fossil was a shocking and unexpected event to most scientists in the world. Scientists had a specific view about evolution. They thought that organisms evolve from a simple state to a more complex state. But that was not the case for the comb jelly which unlike what scientist thought was a very complex specie. It was so complex that it had a nervous system and tissues. But that was not the only misconception that they had to face. Another problem was that scientist believed for so long that the sponge was the first animal fossil, but this discovery has changed the order of species in the tree of life. They could not find the date of when Comb jellies have first existed. But if there existence predates the existence of…
In addition to this information science uses geological and fossil records to explain the changes and diversity that have happened between species over time,through the concepts of natural selection. Scientists believe each fossil is a piece of evidence about the way species adapted and the changes that took place over a period of time.…
Paleontology - Fossils provide a record over time of how living things have evolved. Fossils that are considered transitional fossils are those that have feature that make them an immediate form between organisms. Provide more evidence for change. Eg: Seen ferns have both features of ferns and gymnosperms.…

The dig had been full of surprises, trying to move the tools and volunteers safely down the 85-foot sinkhole had been a challenge. Moreover, the fossils found were well over 100,000 years old. The animals included an American lion, camel and mammoth. While the discovery in northern Utah was unique with over 300 complete fossils found to date, it was minor compared to what Samantha was looking at. As Mark her graduate student continued to remove small particles of sediment with a dentist pick, Samantha stood in wonder watching…
In this activity you’ll make use of some of the techniques and evidence that paleontologists work with to determine the identity of different fossils to establish the particular time period in which those creatures lived.…
BI. 8. e Students know how to analyze fossil evidence with regard to biological diversity, episodic speciation, and mass extinction.…
There are some incredibly specific items that need to be present in order for fossils to be procured, and they are only found in water, caves, or volcanoes. There is also a geological an scale, there needs to be dating, relative and absolute, by finding this fossils you now possess a better view of the times and are able to reconstruct ancient environments, which include climate and habitat reconstruction. Water needs to be present including sand, generally these are found around or in a lake, then there are caves, and volcanoes are an area because of the ash are the conditions and places for fossilization.…
Spearheaded by the Germans discovery of the skullcap and limbs, archaeologists gather information, make inferences, and use their imaginations to construct how things use to be. The conditions of the fossils let us know the kinds of conditions people/animals lived in. This can be problematic because for example, Neanderthal bones and deer bones were mixed together with some of the same marks. An archaeologist could have mixed up the bones and given the Neanderthal a characteristic of life that isn’t accurate to them. This could be the case for any fossil that isn’t easily identifiable and archaeologists have to use their “imaginations.”…
The author and his colleagues specifically chose to focus on 375 million year old rocks in their search for fossils because this was the time frame that provided fish that would be useful to study from. The 385 million year old rocks provided fish that look too similar to the ones we have now and the 365 million year old rocks have fossils that don’t resemble fish. The 375 million year old rocks, however, provide fossils that show the transition between fish and land living animals. Sedimentary rocks are the type of rock that preserves the fossils. Limestone, siltstone, shale, and sandstone are examples of this. The reason why these rocks are the best at preservation is because they are formed by a process that includes the movement of lakes, rivers, and seas. A rock in a body of water has the potential to fossilize because after the gradual compression on the layers in the body of water forming, chemical processes are still happening.…
