I. The Edvidence of Fossils A. (28-1) The Formation of Fossils 1. Fossil: The actual remains or any trace of an organism that lived at some time in the past. 2. Petrifaction: The process by which the body of a dead organism is slowly replaced by dissolved minerals. 3. Mold: A rock as a hollow form; Cast: A copy of the external form of the original organism. 4. Imprint: A type of fossil formed when an impression made in mud by a living thing is preserved when the mud is transformed into rock. B
Introduction to Fossils The word fossil means: a preserved impression, imprint, or trace of living organisms from the past. The Latin term Fossilis means to be dug up. The first fossils were found in Ancient times by the Romans and Greeks who thought the bones belonged to giants and dragons. The first recorded fossil was a Megalosaurus (a carnivorous dinosaur) found by Thomas Pennyston. Pennyston later gave it to Robert Plot in 1676. Plants and all types of animals can turn into fossils. But most
into a sedimentary rock. This process would sometimes take up to millions of years; therefore fossils do not form easily. However the fossil record is one of the strongest lines of evidence for evolution. It provides Paleogeologist a unique view into the history of life by showing the features of life in the past. Paleogeologist usually discovered fossils near the earth’s surface, “if a preserved fossil escapes destruction by geological forces, it may become exposed by erosion” (text book 103). Forbes
Fossils can be divided into two categories, body fossils and trace fossils. Body fossils encompass preserved remains of an organism, such as bones, claws, teeth, skin, embryos, muscles, tendons, organs, and blood vessels (Col). Trace fossils are the indirect signs of life that give evidence of the organism’s presence, such as track ways, teeth marks, gizzard rocks, coprolites, burrows, and nests, which leave an impression behind after moving over a surface of soft sediment (Col). These fossil categories
study of trace fossils is a valuable tool for unlocking the past biology of the planet, and giving information on behaviour, movement, and feeding patterns. The Mesozoic era, or the “Age of Dinosaurs”, ranged from 252-66 Ma and saw the world dominated by huge reptiles, some of which have been preserved in the fossil record. Over the years Australia has produced very informative dinosaur fossils, some of which are body fossils, but others being trace fossils, usually footprints. Body fossils have proved
INTRODUCTION: Fossil fuels are formed from the organic remains of prehistoric organisms, like plants and animals. All fossil fuels take over millions of years to fully form into a usable energy source; which is where the problem begins. Ever since the first usage of fossil fuels back in the late 1850s, the demands for fossil fuels have sky-rocketed to astronomical proportions. Ever since the Industrial revolution, fossil fuels have been used to power nearly everything. The fossil fuels were used
remember the gas shortage of the 1970s will realize what could happen if we run out of fossil fuels without a viable alternative. Today, fossil fuel reserves are getting harder to extract and are of lower grade and insufficient volume to meet global demand. Concern about fossil fuels and their effect on the environment are becoming more important. So how can the United States lessen its dependence on fossil fuels? To truly solve the problem, it will be necessary to change much of our infrastructure
Marry Anning and the Fossil Hunters Despite the fact that Mary Anning's life has been made the subject of several books and articles, comparatively little is known about her life, and many people are unaware of her contributions to palaeontology in its early days as a scientific discipline. How can someone described as 'the greatest fossilist the world ever knew' be so obscure that even many paleontologists are not aware of her contribution? She was a woman in a man's England. Mary Anning
Fossil Discoveries in Kansas 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
1. Fossils are commonly thought to be the “evidence for evolution” but there is so much more. Use examples to illustrate one of these other lines of evidence, being explicit in how it relates to the tree-like branching pattern of evolution. The molecular record is another line of evidence for evolution. Molecular records show a stronger evidence for evolution by comparing the DNA of different species. Even though fossils that are similar gives a physical relation to another, species DNA show more
Multi-Regional Continuity: The Fossil Evidence With regards to the multi-regional continuity model of human evolution, there is without a doubt a preponderance of fossil data that supports the diverse origins of Homo sapiens in different regions of the globe. Skulls displaying a wide variety of mixed modern and archaic features have been found in every corner of the world. The mere existence of these fossils is evidence enough to prove that human evolution was far less cut-and-dried a process than
The Dangers of Fossil Fuel Use Merriam-Webster Collegiate Dictionary defines the term fossil fuel as “a fuel, as coal, oil, or natural gas, that is formed in the earth from plant or animal remains.” The major fossil fuels include coal, petroleum, and natural gases. Here in the United States, and all over the world, fossil fuel functions as an extremely beneficial resource. We use gas to fuel our cars and depend on electricity produced from coal and oil to heat and cool our homes. But, these
There are three main fossil fuels; oil coal and natural gas were all formed hundreds of million years ago before the time of the dinosaurs (Energy Quest, 2012). The period of time that the fossil fuels were formed was the Carboniferous Period. It got the name from the word “carbon” which is the basic element in coal and other fossil fuels (Energy Quest). According to (Energy Quest, 2012) these fossil fuels were formed in prehistoric times from a material called peat which after enough pressure
knowing that you are using it? That is usually the case with fossil fuels. We use fossil fuels all the time and we probably don’t even realize that we are using them because they have become so common in our everyday lives. They help us carryout our lives in multiple ways. They are very important and we must be careful of using it so much because they could run out eventually. Fossil fuels are coal, gas and oil. They are called fossil fuels because they are made from the remains of prehistoric plants
to these fossil fuels billions would perish. This is a reality that we could experience soon when we run out of fossil fuels. Fossil fuels have become the dominant source of energy for the world, but does that mean we shouldn’t try a less archaic, and dangerous form of energy? The burning of fossil fuels has caused a plethora of problems for mankind and the world. Many medical issues have arose since their use in the late 1800’s, the condition of our environment is pitiful due to fossil fuels, and
evolutionists use to describe the theory of evolution. One of those many ways is the fossil record. The fossil record is fossil record, history of life as documented by fossils, the remains or imprints of the organisms from earlier geological periods preserved in sedimentary rock.1 I shall begin by telling you what I believe. I do not think that the fossil record is of any help to evolution. I trust that the fossil record is, in fact, the greatest evidence against the evolutionary train of view. When
Sahelanthropus Tchadensis Fossil: Earliest Hominid In July of 2001, a group of archeologists discovered the skull and jaw bone of the oldest member of the human family. The skull is a new discovery and was found in the Djurab Desert of Northern Chad by a group of archeologists lead by Michel Brunet, and is thought to be six to seven million years old (Walton). The age of the skull and jaw bone were approximated through the association of the fauna that were found with the fossils (Brunet). The skull
Impact of Fossil Fuels Fossil fuels cause pollution, smog, and the greenhouse effect. Fossil fuels really do negatively impact our environment, especially when it comes to global warming, Although there is controversy over whether or not fossil fuels are causing the planet to warm, or whether it is warming naturally, there is significant research that supports the former hypothesis. When fossil fuels are burned, they emit different levels of carbon dioxide. The burning of fossil fuels has
Fossil fuels are “highly combustible substances formed from the remains of organisms from geologic ages” (327, Withgott, Laposata). When it comes to fossil fuels there are three major types: coal, natural gas, and oil (328, Withgott, Laposata). With fossil fuels you need to know how they are formed, where deposits are, how to extract the resources, and finally how society uses them. Knowing these things will give people a better understanding on the impact of fossil fuels. Fossil fuels provide most
The world is dependent on fossil fuels as the prime source of power to meet our energy demands. What are fossil fuels? “Fossil fuels come in three major forms-coal, oil, and natural gas. Because fossil fuels are a finite resource and cannot be replenished once they are extracted and burned, they are not considered renewable.” - (United States Environmental Protection Agency) When the supply of fossil fuels is completely exhausted, what will we rely on to meet our energy needs? An alternative option
