Boom, thod, rawr! Wow, a dinosaur! Well, that what I would have said if I heard those noises. Dinosaurs were the first living organism to walk the earth. Their dynasty lasted for 200 million years and was separated into three different periods: the Triassic, Jurassic, and Cretaceous. The Cretaceous period was the final period of the dinosaurs and to have a better understanding of this period we must look at the climate and the geographical landscape, then we must have knowledge on the many things that lived during this time (dinosaurs and unique sea animals), and finally how the Cretaceous came to an end. The Cretaceous was made up of tropical and subtropical climate throughout the globe. These two types of climates controlled the Earth causing it to have hottest temperatures during the …show more content…
During the Beginning, the Cretaceous was cool and progressively started heating up. By the mid-Cretaceous it was at its hottest point but died down as the cretaceous period was ending. Though it was cooler in the beginning and end, the climate was still much warmer than today’s climate. During the Cretaceous there were two supercontinents, Gondwana in the south and Laurasia in the north. “Antarctica, Australia, India, Madagascar, and several smaller landmasses were joined in Gondwana in the south, while North America, Greenland, and Eurasia formed Laurasia” (Hansen, Koch). By the end of the Cretaceous many of these adjoined landmasses split up forming a geographical map much like today's. The few differences between the end of the Cretaceous and present day was that South and North America were not connected

Time Traveling

...travel back in time. I would travel back in time to the time period of 1920s-1980s in the United States of America. Another reason why I would travel back in time would be in the time period of 1776-1820s in the United States of America. Then my final destination would be the Jurassic Age to see the dinosaurs. As you were reading/hearing what I said I hope that you assume that I like U.S.A. history and how dinosaurs were like. I would see a pleather of things in the time period on 1920s-1980s. For instance, I would get tutored by Albert Einstein himself. Also I will also purchase ten pairs of Back to the Future shoes, and then sell them in the present for profit. I will also see what Northern Cambria (Spangler/Barnesboro) was like. Throughout these years that I would travel, I would get myself different types of suits and get a mint-conditioned Johnny Cash Album –the rare one. The next time period would be from 1776 to the 1820s to see what old America was like. For instance, I would look for George Washington to see what he looked like and to hear how he spoke. Next I would see the Declaration of Independence being made and actually be part of their conference for the Declaration of Independence. Also, since I am a coin collector, I would take hundreds of the first coins that were made in the U.S.A. I will also, from a distance with binoculars, watch how the War of 1812 unraveled and took form. Most likely, the final destination for now…, would be the Jurassic Age. During this...

Ouranosaurus Research Paper

...A French paleontologist by the name of Philippe Taquet named this approximately 110-115 million-year-old dinosaur genus in 1976. The bones were discovered in the Gadoufaoua beds of northeast Niger, Africa just ten years earlier. There are currently two nearly complete skeletal structures associated with this dinosaur; both found in the southern Sahara Desert, and one of them Taquet researched. This paper will continue to discuss the Ouranosaurus in its entirety. It will start with background information, including how to pronounce its name, what it looked like, how it was classified, and which dinosaurs it was similar to. The paper will end with more descriptive aspects, such as when and where the dinosaur lived, what and how it ate, who its...

When Asteroids Strike

...(Tagliaferri, 1998). Scientists were lucky to record this data via satellite to study the force an asteroid can have when impacting firsthand. There is evidence of asteroid impacts covering the surface of the earth and other surrounding planets in space. There are also many theories involving asteroid impacts causing mass extinctions on Earth, the most common being the extinction of the dinosaurs 65 million years ago (deGrasse Tyson, 2005). Most of the impact evidence shows that the earth has been attacked by these asteroids since its formation billions of years ago. Evidence all around us tells us that the Earth will be struck, and another major asteroid impact will occur. The most common and highly argued impact event is the one that may have wiped out the dinosaurs. This event in itself has many theories, but the one common element in most sound dinosaur extinction theories is that a major impact event occurred around the same time the dinosaurs stopped roaming the Earth. Most of the scientific community agrees that an asteroid impact did destroy the dinosaurs. Some scientists; however, claim that the dinosaurs were dying off well before the asteroid strike, due to climate changes, and that the impact only “finished them off” (Archibald, 2005). This very well could be...

Evolution Argumentative Essay

...Comp 101 Argumentative Essay Did you know that 58% of Americans believe in Evolution? Why do they believe Evolution over Creation? Because they don’t want science to be mixed around with all the “emotional fluff” that is supposedly found in Christianity. Evolution and Christianity are both philosophical explanations, meaning you can’t test them, but you can have faith and believe in them, trusting in the evidence found. The Creation theory is the belief that God created the world and everything in it in a 7 day week. The Evolution theory is the belief that the world was created without God by “less complex” life forms gaining new DNA through mutation, gaining new traits, so over a long period of time they become “more complex, previously...

Int1 Task 1

...Integrated Natural Science (INT1) Task 1 The Changing Nature Of Science Evolution Evolution :- All living beings have developed over time from ancestors through a series of changes. That life has changed over long periods of time, with all forms of life related to one another, is a scientifically well-established fact. There are two aspects of evolution today. First, evolution is the organizing principle for all of biology. Just as we are offspring from our parents, and our grandparents before them, and so on, all living organisms today are inclined from organisms that lived in the past. Understanding how and why these ancestor-descendent lineages have changed through time helps us appreciate the diversity of life we see today. Genetics, anatomy, physiology, neurology, morphology, and behavior all of these aspects of living organisms have evolved through time. The study of the evolutionary processes that produced these traits provides the comprehensive framework for understanding them. Theory Of Evolution Evolution Theory: - Evolution is technically defined as: "a gradual process in which something changes into a different and usually more complex or better form." As it is most famously used, "evolution" is the process by which an organism becomes more sophisticated over time and in response to its environment. The Theory of Evolution is currently the most popular concept of how life reached its current state. Evolution as a biological mechanism is driven by natural...

Primates: The Evolution Of The Homo Sapiens

...they or their descendants became apes and modern humans. The divergence of this group, called "Dryopithecus" (arboreal apes), resulted in the formation of several genera, one of them, the Ramapithecus. Since they have some hominoid characteristics, many anthropologists believe that these hominids were a specific ancestor of the human being. However, others reject this hypothesis and believe that the final divergence between human beings and apes occurred 5 million years ago, so that Ramapithecus could very well be a common ancestor of the apes and the human being. The dental arch of Ramapithecus is smaller than that of the simians, this suggests the shape of the human dental arch. The wear patterns of the teeth of the individuals of Ramapithecus suggest that in addition to the teeth, they also used their hands to crush the food (Columbia Electronic Encyclopedia). There is little fossil evidence of the presence of apes of the last 8 million years, but there are two demonstration lines that have solid arguments to point out that the hominids separated at the beginning of this period. The first, as we said, consists of the fossil remains of the first hominids (dryopithecus - ramapithecus), recovered in East Africa since the mid-1970s. The second line consists of biochemical tests that show a very close genetic relationship between humans and African apes. The relationship arises from the shape of the chromosomes, the DNA sequences and the similarity of the proteins. "The more fossils...

Remarkable Creatures Essay

...The Remarkable Tale of Mary Anning: An Analysis of Remarkable Creatures and its Merit as Historical Fiction Novels can do more that simply tell stories. Novels can enhance or emphasize thoughts and ideas. They can excite a wide variety of emotions. They can be the product of imagination, or they can be influenced by historical fact. Whether or not the events in a novel are true is left entirely up to the author, but it is truly an incredible feat to take a piece of history and turn it into a work of fiction that is plausible and logical. For our Senior Seminar, we have studied the aspects of fiction that have a basis in historical fact. They do so by applying certain literary devices that are necessary to the historical fiction genre. The novel I chose to research and present on is entitled Remarkable Creatures, by Tracy Chevalier, author of Girl with a Pearl Earring and The Last Runaway. This work of historical fiction tells the story of Mary Anning, one of the first recognized female paleontologists whose discoveries changed many views on the world and how it began. Remarkable Creatures is a biographical novel, as it concentrates on the experiences that Mary Anning had during her lifetime, the people she meets, and the incidents that occur in her life. This essay will evaluate Chevalier’s work on the basis of its merit as historical fiction. Remarkable Creatures belongs in this category because it Chevalier implements the critical terms of the genre in numerous and intricate...

Evolution

... evolution is the binding force of all biological research. It is the unifying theme. In paleontology, evolution gives workers a powerful way to organize the remains of past life and better understand the one history of life. The history of thought about evolution in general and paleontological contributions specifically are often useful to the workers of today. Science, like any iterative process, draws heavily from its history. It is a FACT that the earth with liquid water, is more than 3.6 billion years old. It is a FACT that cellular life has been around for at least half of that period and that organized multicellular life is at least 800 million years old. It is a FACT that major life forms now on earth were not at all represented in the past. There were no birds or mammals 250 million years ago. It is a FACT that major life forms of the past are no longer living. There used to be dinosaurs and Pithecanthropus, and there are none now. It is a FACT that all living forms come from previous living forms. Therefore, all present forms of life arose from ancestral forms that were different. Birds arose from nonbirds and humans from nonhumans. No person who pretends to any understanding of the natural world can deny these facts any more than she or he can deny that the earth is round, rotates on its axis, and revolves around the sun. Evolution is a force than nothing can escape. Communities evolve constantly and although there is no standard of where a society should be at any...

En1320 Final Research Paper

...EN1320 Final Research Paper | The Lord God took the man and put him in the Garden of Eden to work it and keep it. (Gen. 2:15, Revised Standard Version) In the beginning man was given the responsibility for keeping the earth. As good care takers it’s our responsibility to ensure the survival of all the animals and plants on earth. The earth is made up of elements, and within those elements are the countless numbers of species, each interwoven within the fabric of life itself. The effects of man on the environment have a negative reaction to all other species. Studies of earth’s history show mass extinction events. Scientist project we are living within such an event. The world is heading toward imminent mass species extinction. A healthy earth may not be possible due to the irreversible effect brought on my man. Endangered plants and animals face the risk of becoming extinct, disappearing completely from the world of living things. Human survival has had such an effect on all other species around them. Hunting, fishing, or gathering may have reduced the populations of many species to levels too low for the species to survive, especially when there is a profitable trade in goods made from wild animals and plants. (Current Issues, 2010) The Earth should be big enough of all plants and animals to thrive but according to the American Association for the Advancement of Science, humans are using about half the available land. (Wilson, 2012) The American Association...

Why Students Matter

...care about the success of their students in examinations and in some cases students who pass through such teachers, especially in terms of emulating their life styles, tend to exhibit behaviors that are detestable by the society Teacher effectiveness influences students’ academic performance. It is not however, very easy to investigate the area of effectiveness in teaching because many hold the view that the concept has. Even, from among those who hold the views that teacher quality should be assessed by student outcomes however, arguments could be made for an emphasis on different types of student outcomes. Teacher quality can be gauged by short- term outcomes such as students’ performance on state standardized tests at the end of the period prescribed for a given academic programs.  Long-term outcomes may be much more difficult to measure but some might argue that the best teachers are those who somehow improve students’ educational trajectories in some important ways. In other words, teacher quality is multi-dimensional and complex in nature and can be measured. Perkins (1974) said that, there is little or no agreement on the criteria that should be used for judging effectiveness in teaching or on how the effectiveness of teaching can be measured. He however, agreed that it is only when the various approaches used to define and measure teaching effectiveness are examined that one would be able to gain a clearer understanding of the concept. Advocating the various ways to...

Psychology Revision Notes

...Memory Without it, you’d be constantly living in one moment to the next. You wouldn’t know who you are, where you came from or where you are going. But what is it? And how does it work? To answer these questions, early memory researchers decided to break memory down into simple structures. The mysterious power of our mind to store images, words and sounds, was reduced into several components. All of these components were then thought to interact through simple processes. Simplifying memory in this way was a necessary step in developing our understanding of how memory functions. From this structured view of memory, two important models of memory were developed: the Multi-store Model and the Working-Memory Model. Section 1: Multi-store model of memory Atkinson and Shiffrin (1968) Do you think you have a good memory? What is your earliest memory? The multi-store model is a structural model which states that memory is made up of 3 distinct, separate stores: sensory memory, short-term memory (STM) and long-term memory (LTM). Each of the stores can be analysed based on three factors: 1) Capacity: how much information can be stored 2) Duration: the amount of time the information can be stored 3) Encoding: how the information is represented by the memory system Sensory memory The first store in the multi-store model is the sensory memory store. This store provides an account of the environment as experienced by our senses. A copy of the stimulus is kept here until we determine...
