Fossils paper Have you ever wondered? How conditions for successful fossilization differ from plants and animals. The data gathered talks about the differences and similarities between plants and animals fossilization. Animals for instance are bigger and their bones don’t break down quite as easy. The plants are somewhat the same and different.
Mammals
Some ways animals get fossilized are they get stuck in asphalt and get buried. It takes a lot of time to fossilize an animal. The bigger they are the longer it takes to fossilize. The different conditions affect fossilization, such as it will be different in a cold climate then in a tropical climate. If a fossil was created in a tropical area it was probably because the mammal fell in
The sabertooth cat, also known by its scientific name Smilodon Fatalis, is considered a true form fossil. A fossil is considered a true form fossil when scientists recover fossils of the actual animal or animal part. These bones were oftentimes subjected to physical processes while still on the surface. These processes include heat, cold, wind and rain.

Fossil preservation has always been the most accurate way to determine what species lived during a specific time period. Through correlations and radiometric dating, time periods have become more accurate and being able to tell what lived during those times became possible. Although conditions have to be correct for fossilization, Pleistocene fossils are widespread and often well preserved. In the La Brea tar pits of present day Los Angeles, hundreds of thousands of preserved bones have been found that give a good idea of the animals that were present during this time. Many of the animals preserved are animals that can still be found today and would be found in the Los Angeles area if not for urbanization. Animals that were present during this time include camels, mammoths, and saber-toothed cats among others (Harris and Jefferson, 1985). Below is a picture of a saber-tooth fossil found in the La Brea tar pits.
The Carboniferous Period was a time period in the Geological Time Scale that came after the Devonian Period and ended at the beginning of the Permian Period. It lasted from 359 to 298 million years ago. The Carboniferous got its name from the large amount of coal deposits that were found during this time scale. In North America, the period is often separated into two, the Mississippian and the Pennsylvanian.
This paper examines a National Geographic news article pertaining to the history of First Americans called, “On way to New World, First Americans Made a-10,000 Year Pit Stop”. The First Americans may have stayed on the Bering Land Bridge after separating from Siberia, which would explain a few things about the genetic variances between the two groups. Why do researches believe first Americans lived on the Bering Land Bridge? Are the reasons to believe in this justified? This paper attempts to answer such questions.
One of the most well-known urban legends told is the story of Bigfoot. Much of the research has shown that there are several names assigned to the mammoth ape. According to Napier (1973), Bigfoot would be the creature found mostly in Northwest America, Sasquatch would be a creature named in British Colombia, the 49th parallel in the north-west states of America and Northern California, and the Abominable Snowman, or the Yeti would be the creature named in the Himalayas. Of course, “Wild Man” and “Savage” have also been names used to identify the creature. There’s been thousands of sightings across the world, but there have also been many misidentifications where those who think they have seen Bigfoot have really just seen an ordinary animal or person. Arment (2006) states an individual’s perception may color the eyewitness account. Such misidentifications include: hermits, fugitives, refugees, bears, gorillas, and simply people making up stories or rumors. In addition to sightings, there have been photos, videos, movies, and TV shows that strongly indicates the possibility of the existence of this creature. Though there is much evidence from sightings, myths, and recordings that Bigfoot exists, there is also much proof that it could all be a hoax. Incorrect sightings have led skeptics to argue over the existence of this being stating Bigfoot is really just a fable. So one has to ask oneself, does Bigfoot really exist or is it just another urban legend?
Did you know, in the state of Oklahoma it is against the law to either hunt or catch whales? Sounds sort of ridiculous when you think logically about it, but according to paleontologists it isn’t that far fetched. Over 65 million years ago Kansas, including the whole Midwest Region of North America from the Arctic Circle to the Gulf of Mexico, was covered by the Sea. Due to the continental uplifts of the mountain ranges in North America during the Pangaea stage, the once shallow sea of Kansas became shut off from the sea-water flow and dried out to what we know it as today. The biome of Kansas over the last 65 million years has become extremely dry and flat, which would account for a once shallow inland sea. For example; Salt Lake City was once in the mist of a glacier that filled the inside “hole” of the City, causing the surface of it to be extremely flat excluding the surrounding mountains.
In 1640 a bog body was discovered by a farmer in Holstein, Germany. This was possibly the first recorded instance of such a discovery, but what is a bog, how are human beings preserved in one, and how are bog mummies different from others? This essay will explain the one-of-a-kind characteristics of a bog and how all of these events can take place in one.
Mummies are made by taking out the insides of the body. In my essay I am going to be stating information on how mummies are made, and the afterlife.

For instance, the whale, the biggest mammal that lives in the water, was found to have had legs and used to dwell on land millions of years ago. While in Pakistan, Phil Gingrich, a geologist and paleontologist, came across a fossil that resembled that of a wolf but had a “bump” on the back of the skull which was found to part of an inner ear,
How might conditions for successful fossilization differ between mammals and plants? Well, fossils and plants have a very different chemical makeup. for example, plants have a soft tissue that would have to have just the right conditions in order to fossilize. On the other hand, a fossil is very hard and solid, therefore they are able to fossilize in much harsher conditions. Fossils have very different ways of being fossilized.
11.) Fossils - are the remains of plants or animals that have been preserved over centuries in the strata or layers.
