Clues to the age of the fossil came from key features in the landscape; such as…
Current research into extinct megafauna and extant Australian species revoles heavily around the finding off fossils. Fossils provide Palentologists with information about the similarities and differences between species, deducing certain evolutionary relationships. Other research includes radiometric dating, providing dates for when fauna died and the possible cause. Ideas about…

Fossils help determine the relative age of strata because when a scientist discovers that fossil they can then place a time frame of when that organism was alive. Scientist’s already have certain time frames that they follow, so when they find a fossils that are within that strata then they can determine when that organism was alive they can then place that organism into that time frame. All three of the localities which are Paradoxides pinus within the Paleozoic Era, Billingsella corrugate which is also in the Paleozoic Era, then there is Perisphinctes tiziani I believe, which is in the Mesozoic Era, and last the Dictyoclostus americanus which is located in the Paleozoic Era, all of these are within the same relative age they are found within the same time frame as each other. The only thing that was missing in the figure on pg.68 figure 3.6 was layer D this may have been because of possible erosion or it may have never deposited at all. That is very likely that it may have existed at one time, but the erosion from may have destroyed it. Although some scientists may argue that fossils are not a good way to determine the age of some organisms I feel as though it is a good way because the fossil is found in that layer of strata so therefore it should be placed in that time frame. The fossils that where found were between the Paleozoic Era and the Mesozoic Era because of this knowledge the scientist can determine that the fossils that were found are probably between 65 million years to 251 million years old. This allows scientists to see how the Earth has changed or evolved over the different Eras.…
The study of fossils is helpful to know in understanding evolution, as it teaches us about our…
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…

The fossils were found nearly every continent. Fossils are still being examined and observed today. Dinosaurs are closely related to the modern birds, who are warm blooded. New evidence has showed that dinosaurs have been known to be cold blooded but evidence has showed differently. New evidence shows dinosaurs regulated their body temperature from an internal stance than using the environment to help regulate their body temperature. Dinosaurs has homologous features of other animals of their time. Research supports that dinosaurs are warm blooded.…
The debate of whether dinosaurs were cold or warm blooded is neither a new nor resolved debate. Since first hypothesized in 1969 by John Ostrom (Anderson, 2009), the debate…
Fossils which are any and all traces of a past life and fossil records are fossilized remains of organisms that lived in the past, and the people that look and study these remains of a past world are paleontologist, they are men and women who study extinct organisms based on their fossilized remains.…
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.”…
3. Paleontology is the study of fossils, including fossilized plants and animals. Fossil are any perceived remains of a prehistoric organism, in this cause an ancient primate. The dig was lead by Dr. Biren Patel and along with a group of scientist, a partial mandible of an early primate was found in the Kashmir region of India. The fossilized mandible was DNA tested and compared to several modern organism in order to determine the closest living relation. The closest relation to the fossils DNA matched to modern day lemurs. However, this is perplexing as…
