The Cretaceous-Tertiary

Improved Essays
Over the course of the Earth’s history there have been five Mass Extinctions, a global event where at least 75% of the life on Earth dies. In most of these events the only life form to survive are bacteria, or other small organisms that can hide from the destructive force that wipes out everything else. The Cretaceous-Tertiary (K/T) is the most recent and most famous Mass Extinction, taking place 65 million years ago. The K/T is the event in which the dinosaurs died in. The cause of this event is debated, however it is widely accepted by most scientists that the K/T extinction was triggered when a giant asteroid or comet struck the Yucatan Peninsula in Mexico killing off close to 80% of life on Earth. This event was totally random and if it

    The frog used to be found covering every part of the forest floor, but by 2002 they were practically wiped out. At first it was dismissed as an overreaction but as the disappearance of the Panamanian golden frog increased, researchers all around the world began to take notice. This event can be described as a “background extinction”. Compared to a mass extinction a background extinction is on a much smaller scale, while a mass…

    Although we most commonly know that the dinosaurs died out from this, there are many other species that went extinct; one of the least commonly known species is called the ammonites. The ammonites are symbolic of how a species can be fit for an environment, but a catastrophe can completely change what is and isn’t fit. The next chapter discusses graptolites, and how their extinction is symbolic of how glaciation can cause extinction. Graptolites went extinct because of a sudden drop in carbon dioxide levels, which caused sea levels and temperatures to decrease.…

    In her book The Sixth Extinction, Elizabeth Kolbert writes that there have been five mass extinctions in the history of planet earth. She asserts that currently the earth is on the precipice of a sixth mass extinction. In contrast with the previous five, according to Kolbert this sixth extinction is almost entirely caused by humans and our exploitation of the earth. In each of the book’s thirteen chapters, Kolbert highlights a particular species that is now extinct and analyzes the causes and effects of its extinction. She explains the scientific history of the concept of extinction.…

    Where climate change is severe and the topography is flat, species would typically have to travel greater distances to find suitable conditions, experiencing greater risks of extinction” (Sandom et al 2014). Results have shown that late Quaternary climate change velocity was related with low modern species endemism of mammal’s amphibian and birds signifying that high extinction rates in the past was more prevalent in more climatically unstable regions. In a report done by Stephen Wroe and his team which studied how Climatic changes influenced the extinction of megafauna he documents how they “used mean annual temperature and annual precipitation anomaly and velocity between the past and the present to represent the…

    Scientists recognized during the late 1800’s and early 1900’s that there was some glacial and interglacial periods which may have correlated with the extinction of specific species. These scientists claimed that the extinction during the Pleistocene ice age may have been the ultimate reason why the large mammals went extinct. However, others disagree with this hypothesis due to the fact that there had been many glacial advances and retreats which had not resulted in the extinction of the megafauna; therefore, there is no reason that the last glacial event would have caused the extinction. The rebuttal to that disagreement, however, is that the mammals alive during the time of the earlier glacial events were different than the mammals alive during the later glacial…

    The Mesozoic Era was a point in time about 252 to about 66 million years ago. During this era, there were three periods. The Triassic period, The Jurassic Period, and The Cretaceous period were all very significant in earth’s evolution. Not just in animals, but in land, plants, climate, and even insects.…

    “Sex, Drugs, Disasters, and the Extinction of Dinosaurs” is an essay authored by Stephen Jay Gould, professor of geology and zoology at Harvard. Gould does a masterful job of catching your attention right away with his title, then taking you on a journey exploring how we can differentiate what is attention-grabbing nonsense and what is valid science. In his essay, Gould explores scientific proposals for the extinction of dinosaurs. This is a question that humanity has pondered for thousands of years, and many speculations have been made. Gould outlines what theories fall into “good” and “bad” science and then explains how he uses the scientific data to build a case for solid, evidence-based theory.…

Lofted debris darkened skies around the world. The planet chilled — and stayed that way for years.…

    The Smackover Formation, a Jurassic system, with a carbonate petroleum source rock, extends over several states including: East Texas, South Arkansas, North Louisiana, Mississippi, South Alabama, and West Florida. The Smackover Oil Field was discovered in Union County, AR, in April 1922 (Weeks, 1938). Later, in 1936 Phillips Petroleum and Company, successfully drilled the first limestone discovery in the field, discovering a new formation to which the field would lend its name (Weeks, 1938). The Petroleum System- From Source to Trap’s defines a petroleum system as the “essential elements and processes, along with genetically related hydrocarbons that occur in petroleum shows, seeps, and accumulations whose provenance is a single active pod…

    The Permian Mass Extinction Introduction There are five major extinctions in history: the Late Devonian, the Ordovician-Silurian, the Permian-Triassic, the Triassic-Jurassic, and the Cretaceous-Tertiary. Known as the Big Five, these extinctions exceeded all others in size and destruction, each killing more than 60% of species from that period. Each one acted as a bottleneck, allowing the survival of only a fraction of the organisms that had been thriving before, from which evolution and life must continue. There was one mass extinction above all that came perilously close to turning the Earth into a lifeless and desolate wasteland.…

    The map is almost uncannily similar to today's: a spray of black dots showing the recorded sightings of a foul grey haze spreading across Europe, from Helsinki to Naples, from Heligoland to Mallorca, and reaching eventually to Aleppo and Damascus – and all of it caused by clouds of ash from an immense volcano erupting far across the sea in Iceland. But this was a map made from data collected in 1783. The volcano was called Laki, it erupted for eight dismal months without cease, ruined crops, lowered temperatures and drastically altered the weather. It killed 9,000 people, drenched the European forests in acid rain, caused skin lesions in children and the deaths of millions of cattle.…

    Evaluative Analysis for Dinosaur Extinction In Stephen Jay Gould’s article, “Sex, Drugs, Disasters, and the Extinction of Dinosaurs,” Gould begins to analyze the difference between science and speculation. In the article, Gould presents that science is considered allowing humans to be able to know and gain knowledge. In “Sex, Drugs, Disasters and the Extinction of Dinosaurs,” Gould begins to state the question of why dinosaurs became extinct and what possible causes could relate to the non-existence of the dinosaurs. The first theory that Gould contemplated for the extinction of dinosaurs could be caused by the sex hypothesis. Gould believed that this theory caused the non-existence of dinosaurs because testes can only perform in certain conditions.…
