Recommended: Extinction of dinosaurs persuasive essay

What happened to the dinosaurs? Why did they disappear? Dinosaurs roamed this earth from around 231 million years ago to 66 million years ago; that’s 170 million years of existence! Some event must have happened to wipe out these prehistoric animals. Many scientists believe an asteroid impact was responsible for the dinosaurs demise. Others contend volcano eruptions had something to do with it. A few others solely believe climate change was the one and only culprit. There are also some outcasts that have their own ideas about the dinosaurs quietus. These questions have intrigued humans since the first fossils of these animals were discovered nearly two centuries ago. Humans are curious beings and always search for answers, which is why there …show more content…

During this time, dinosaurs came and went, and through the years, they evolved and some died out. Scientist track dinosaurs evolution and their extinction through giving each advancement a time period. These time periods include the Triassic, the Jurassic, and the Cretaceous. Both the Triassic and the Jurassic periods had extinctions but not the mass extinction most people are aware of. The most widely viewed dinosaur extinction period was in the Cretaceous. Charles Q. Choi explains that the Cretaceous mass extinction is known as the K-T Boundary. K-T marks the end of the Cretaceous (K) period and the beginning of the Tertiary …show more content…

However, there are a few scientists who stray from popular belief and search for answers elsewhere. Gianluca Brocchi wrote an article explaining that Darwin’s theory of survival of the fittest could have something to do with dinosaur extinction. In “The Case of the Disappearing Dinosaurs,” Bocchi wrote that dinosaurs and mammals may have been pitted against each other in an environment with very little supplies (1). Because of this, there was a conflict between these animals. Dinosaurs were powerful creatures but warm-blooded mammals were more adaptable to changing climate. They were smaller, smarter, and agiler creatures; evolution was on their

    The question of what caused the extinction of megafauna during the Late Pleistocene period is one that archaeologists have struggled to answer for decades, but why should it matter? Discovering with certainty the cause of megafaunal extinction would simultaneously prove or disprove any of the proposed implications of each existing theory regarding this massive extinction.

  • Cannibalism and Feeding Habits of Dinosaurs

    ...ories of why dinosaurs went extinct abound, and as there is no theory yet to be truly confirmed as the “right one”, my theory of dinosaur cannibalism is also purely anecdotal. The discovery of the cannibalistic Majungatholus atopus in Madagascar is an important scientific find because it confirms a long-standing theory of cannibalism among certain carnivorous dinosaurs. Behavioral patterns of extinct animals are difficult to establish; however, these bones give authentication to previous unfounded beliefs about the ancient feeding practices of some dinosaurs.

  • The Permian-Triassic Extinction 250 Million Years Ago

    615 Words  | 2 Pages

    The Permian-Triassic Extinction is a mass extinction that occurred between the Permian and Triassic geologic time periods approximately 250 million years ago; it is the deadliest of all extinctions that have occurred on Earth. In addition, during the Permian-Triassic extinction the continents of today existed as one supercontinent known as Pangaea. This was the first time in history where continental or land mass exceeded that of the ocean. This was also before dinosaurs of the Triassic period roamed Earth, during this time animals such as the therapsids, and Synapsids such as the Pelycosaurs, insects and amphibians also occupied Earth. Fauna that existed during the Permian period includes Gymnosperms, or seed producing plants such as the Conifers. Other animals that existed during this time include marine life such as brachiopods (clams), bryozoans (coral-like skeletons), bony fish and sharks, as well as crinoids (sea urchin like creatures). According to National Geographic, about 90 percent of all the animals and fauna of this period perished, the marine life was hit the hardest wi...

  • Warm Blooded Versus Cold Blooded Dinosaurs

    1534 Words  | 4 Pages

    Dinosaurs were first believed to be cold-blooded because they were thought to be related closely to reptiles which are cold-blooded creatures.  Cold-blooded animals don’t actually have “cold” blood, instead they rely on the temperature from their environment to regulate their own body temperature.  They do this by taking advantage of external heat by basking in the sun, and by lying in the shade to cool down.  A more correct term is “ectothermic” which means “heat from outside.”  On the other hand, a warm-blooded animal creates heat internally by chemical reactions inside their body.  They are able to regulate their body temperature internally instead of relying on their environment.  Author of the article, “Dinosaurs: Warm or Cold Blooded?” Beverly Eschberger explains, “endothermic animals have a continually high requirement for food to fuel the heat generation.  Providing they can find food their constantly-optimum body temperature means that they can stay active even when it is very cold” (par 3).          Even though it was believed that dinosaurs were closely related to cold-blooded reptiles, most dinosaurs had similar behaviors of a bird which is a warm blooded animal.  Believing dinosaurs were warm blooded would help explain the reason why dinosaurs were so dominant and plentiful for such a long period of time.  There are many other factors that play a vital role in ...

  • What Are Dinosaurs?

    776 Words  | 2 Pages

    We use dinosaurs to represent the changes in nature that have occurred throughout time. Studies found that although the “oldest rock did not show evidence of life, the progression of plant and animal life that changed in recognizable intervals, from ancient life, age of reptiles to the age of mammals” (Dino Nature Metaphor, slide 6), measured the age of the earth. When we think of dinosaurs in relation to nature, we think of that very powerful force that controls the cycle of life. Nature was able to yield such magnificent ferocious creatures that walked the earth and then take them back when they served nature’s purpose. Dinosaurs fit perfectly in nature’s constant

  • The Warm and Cold Blooded Nature of Dinosaurs

    1118 Words  | 3 Pages

    The debate of whether dinosaurs were cold blooded or warm blooded has been ongoing since the beginning of the century. At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species. In this essay, I am going to give supporting evidence of dinosaurs being both warm and cold blooded. I will provide background information on the dinosaur that was discovered and what information it provides scientists.

  • The Ecological Impact of Native Americans in Eastern North America

    1098 Words  | 3 Pages

    Fossil records from 12,000 years ago show the appearance of the Large Mammals followed by Paleoindian in Eastern North America. Another piece of the fossil record shows that the appearance of Paleoindian brought about the disappearance of the large mammals. Some people feel that, "there is evidence to suggest that rapacious hunting practice of the paleohunters in North and South America 12,000 years ago may have caused…The demise of the very animals they hunted" (Powell 1987). The evidence Powell suggests is that the extinction of a large mammal is usually followed by the appearance of humans in the fossil record. This coincidence is not only seen in the fossil records of North and South America but Europe and Asia as well. Powell shows that as human populations increased local extinctions of large mammals occurred. This was probably due to the fact that there were not many predators that could hunt the large mammals except man. For this reason it is also highly like likely that man and large mammals did not co-evolve which ultimately resulted in the extinction of large mammals.

    ...r optimum temperatures, hot climate caused the dinosaurs to heat up beyond their optimum. However, the heat didn’t kill them, but sterilized the males, because their testes functioned at certain temperatures. Gould argues that this theory is untestable, and the experiments with the influence of extreme temperatures on modern alligators do not necessarily explain the extinction of dinosaurs. Furthermore, many questions are not answered because of the absence of evidence. Gould states that this theory is another example of bad science.

  • Sex Drugs Disasters And The Extinction Of Dinosaurs Analysis

    He explores the theories that a rise in temperature could have made the reptiles of old infertile, or that the dinosaurs ate flowering plants that acted as drugs, causing the beasts to overdose. He goes on to examine a third theory, that of an asteroid hitting the earth and causing a cloud of smoke and dust to cover the sun, dropping temperatures and killing not only the dinosaurs, but much of the life that was present on the Earth at the time. Gould himself leans toward the last theory, citing evidence and research to back his point. All of this, he delivers with an air of humor, saying things such as “How can we possibly decide whether the hypothesis of testicular frying is right or wrong?” (par 21). While the theory of infertility of dinosaurs comes from the idea of rising heat, Gould’s wording here brings to mind a funny image rather than a worldwide epidemic. Using humor again, Gould says “If you talk just about asteroids, dust, and darkness, you simply tell stories no better and no more entertaining than fried testicles or terminal trips” (par 26). Not only does he cast aside the first two theories as useless frivolities, he sets the stage for proving why the asteroid theory is better, using humorous language to do so. A humorous essay such as Gould’s is fun to read, while keeping a basis in

  • Dinosaurs are not Extinct

    As time goes on, more and more fossil record of dinosaurs are richly known; more and more relative research project work on. An encouraging imagination that species of dinosaurs are not extinct and they evolve to birds was emerged. Dinosaurs are still here. They are still all around in the Human Age. It sounds crazy. Nevertheless, it seems clues are everywhere. There is a kind of dinosaurs, call Sauroposeidon, could raise its massive head over eighteen meters into the air, but this was only possible because their neck bones were so light, almost 85% hollow (name). Like Sauroposeidon, other kinds of dinosaurs’ bones were honeycombed with empty spaces. In fact, everybody already knows that birds have hollow bones as well, and a lot of people believe that’s an adaptation for flight. Scientists learned that birds inherited their hollow light bones from their extinct ancestors, gigantic dinosaurs. And there is another clue.

    Some scientists believe that mammals out competed dinosaurs for food and other resources. The last theory that dinosaurs died due to a large amount of volcanism comes up in scientists list of theories as well. Many different theories of why dinosaurs went extinct include extinction by asteroid, mammals outcompeting dinosaurs, climate change and volcanism. The most popular theory of dinosaur extinction, the asteroid theory, says that dinosaurs died out because of a single, giant asteroid. They say that the asteroid that struck the earth near the Gulf of Mexico went 43,000 mph and spanned six miles wide (Erdman).

  • Jurassic Period

    The Jurassic period is known as one of the most interesting periods of time in earth’s history, mainly for the awe-inspiring creatures many of which have gone extinct, the most remarkable being the dinosaurs. Life in the ocean during this time was also extremely diversified and amazing for the creatures it beheld. The Jurassic occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period within the Mesozoic Era. The supercontinent of Pangea began to drift apart during this time. Right before the Jurassic period began, a major extinction event occurred wiping out much of the life on earth. The events that unfolded afterwards gave life to a new planet.
