Why did the Dinosaurs Go Extinct?
What is extinction? Dinosaurs are the largest species to be extinct. There are many different theories of how the dinosaurs went extinct. Some of those theories are an asteroid hit earth causing massive amounts of iridium to fill the air, climate change very intense causing them to go extinct, mosquitos that contain malaria could have forced the dinosaurs into extinction, and a volcano could have erupted causing iridium to fill the air.

The temperature dropped to 47°F and lasted for at least 3 years after impact.
There are two more theories of how the dinosaurs went extinct, one of them are malaria killed them. A fossil was recently found of a mosquito containing malaria that is at least 20 million years old. Earlier forms found in biting midges are at least 100 million years old. The type of Malaria found in the fossil was the first fossil record of Plasmodium malaria. The last theory is that a volcano killed the dinosaurs. The the theory is that 65 million years ago a volcano explodes with rich iridum and magama spewing out like flood waters. The iridum and magama piled up more than 1.5 miles thick over one million square miles. It spread iridium around the world. Also sunlight-blocking dust, soot, and greenhouse gases filled the air. There are many different theories of how the dinosaurs went extinct. Some of those theories are an asteroid hit earth causing massive amounts of iridium to fill the air, climate change very intense causing them to go extinct, mosquitos that contain malaria could have forced the dinosaurs into extinction, and a volcano could have erupted causing iridium to fill the air. My favorite theory is the asteroid theory. The most significant part of this theory is when the asteroid hit earth because the asteroid collided with earth. The impact was so intense that it caused a whole species to go

    The possibility if a meteor strike as the cause of extinctions is discarded, something that most specialists agree on. There is no evidence of any meteor crater big enough or recent enough to be accountable for it; there are no “elements that are common extraterrestrially but less so on Earth, such as iridium, and no sign of a tsunami or other phenomena following the impact.” The extinctions where also very selective and occurred over a very long period of time. If a “one shot” catastrophe had been the cause it would have affected all species at the same time and in similar

  • The Extinction Event and Life in the Post-Apocalyptic Greenhouse

    840 Words  | 2 Pages

    The biggest mass extinction of the past 600 million years (My), the end-Permian event (251 My ago), witnessed the loss of as much as 95% of all species on Earth. Key questions for biologists concern what combination of environmental changes could possibly have had such a devastating effect, the scale and pattern of species loss, and the nature of the recovery. New studies on dating the event, contemporary volcanic activity, and the anatomy of the environmental crisis have changed our perspectives dramatically in the past five years. Evidence on causation is equivocal, with support for either an asteroid impact or mass volcanism, but the latter seems most probable.

  • 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 ...

    In the essay “Sex, Drugs, Disasters, and the Extinction of Dinosaurs” scientists come up with several theories of how the dinosaurs could have possibly become extinct. They tell three of the leading theories as to how they think the dinosaur era extinction happens. The whole thing is a big conspiracy. These theories are government cover-ups to keep us from knowing things. The government knows things that they don’t want us to know, but I already know what happened. The extinction of the dinosaurs are the effect of alien activity on and around Earth.

  • Sex, Drugs, Disasters, and the Extinction of Dinosaurs by Stephen Jay Gould

    771 Words  | 2 Pages

    “Sex, Drugs, Disasters, and the Extinction of Dinosaurs” is written by Stephen Jay Gould, professor of geology and zoology at Harvard. This essay is one of more than a hundred articles on evolution, zoology, and paleontology published by Gould in national magazines and journals. It tells about scientific proposals for the extinction of dinosaurs – a confusing but an exciting problem that humanity tries to solve. By analyzing and describing each of the claims for the reptiles’ demise – sex, drugs, and disasters – Gould differentiates bad science from good science and explains what makes some theories silly speculations, while the other, a testable hypothesis.

    Earth has gone through five fully major extinctions before. We currently are in the process of Earth’s sixth mass extinction. This mass extinction is closely related in severity to the extinction of the dinosaurs. Earth’s extinctions are broken into three different areas. The first area was the large number of animals caught by hunter-gathers. The discovery of agriculture led to the second area of extinction, wildlife habitats. These wildlife habitats were destroyed due to humans starting to stay in one area.

  • The Asteroid Theory: The Extinction Of Dinosaurs

    575 Words  | 2 Pages

    Mysteries are so fascinating because mysteries are like taking unknown information, discovering it, and making it known. Discovering why dinosaurs went extinct is looking into the discovery of their extinction and why they are extinct. Dinosaurs were the largest reptiles known to man, and around 65 million years ago, dinosaurs became extinct. Two-hundred and thirty million years ago the first dinosaur-like creature roamed the earth. These creatures were the top of the food chain, and it is crazy to think that the most dominant of all species became extinct. But there had to be either a theory such as ‘The Asteroid theory’, ‘The Ice Age theory’, or the ‘Volcano Theory’ to explain such drastic measures for the entire population to die out. This is where the mystery takes place and begins.

  • The Extinction of The Dinosaurs

    1255 Words  | 3 Pages

    Many different theories exist as to why the dinosaurs went extinct. We know for sure most dinosaurs died out around 65 million years ago. The majority of scientists agree on a number of theories as to what brought the end of the dinosaurs. The most popular theory is that an asteroid ended the reign of the dinosaurs. Another theory, massive climate change in the pre-historic atmosphere, caused all the dinosaurs to die. 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.

  • Jurassic Period

    Almost 23% of all families, 48% of all genera (20% of marine families and 55% of marine genera) and 70% to 75% of all species went extinct (Beaz). Although the cause of this mass extinction is debatable, many speculate that global warming was the killer. Because Pangea was breaking up into Laurasia and Gondwanaland, there was widespread volcanic activity caused by the rifting, increasing atmospheric carbon dioxide. The massive release of this greenhouse gas increased global air temperatures and resulted in acidified oceans along with rising sea levels. If this is the case, the life in the ocean would have died at a significant rate. Many families of brachiopods, gastropods, bivalves, and marine reptiles became extinct (Rafferty). An important trace fossil known as the phylloceratid ammonoid was able to survive, and they gave rise to the explosive radiation of cephalopods later in the Jurassic Period, as well as evolved into many different forms during the later Cretaceous (End Triassic Extinction). This extinction event ranks fourth in severity of the five major extinction events over geologic history

    Because the CO2 levels are rising, the ice caps are melting and many more animals can become extinct. When pangea started splitting, there was a lot of volcanic activity, which cause the death of many dinosaurs. A meteor also hit earth and the mass extinction of many land and marine animals happened. There have been five mass extinctions in Earth’s history. The worst one wiped out ninety-six percent of marine life and seventy percent of land organisms. This took millions of years to recover.
