The evidence clearly indicates that this theropod had lung and respiratory mechanics similar to that of a crocodile—not a bird. There was evidence of a diaphragm-like muscle separating the lung from the liver, much as you see in modern crocodiles. These observations suggest that this theropod was similar to an ectothermic reptile, not an endothermic bird. Did feathered dinosaurs exist?
The dinosaur extinction theory – a large asteroid impact and a giant volcanic eruption at the end of cretaceous – also supports that dinosaurs were cold blooded, when the dust due to the meteorite covered the earth, then the sun light could not penetrate the smoke and dust, thus sunlight did not enter the earth for many years, this lead to the drop in temperature on the land, as dinosaurs were cold blooded they could not raise their body temperature without sunlight and hence were
In the passage, the author claims that the Edmontosaurus migrated south in order to survive. However, the lecture refutes the view in the reading and argues that the arguments are not convincing. First of all, the passage establishes the view that Edmontosaurus diet drove them southward because there would have been no plants alive in the North Slope. By contrast, the professor in the lecture contends that Edmontosaur does not need to migrate to South to get food. Edmontosaur can get good quality of plants since it was 24 hours of sunshine during summer.
In specific, Hibbard’s argument regarding the inability of Galapagos tortoises, modern relatives of giant tortoises that went extinct, to survive harsh condition provided a counter argument. To elaborate, if Martin’s theory was correct then Hibbard argues that Giant tortoises would have been able to survive harsh weather conditions, eventually falling victim to human predation. Yet his study demonstrates that future descendants of the Giant tortoises died upon immediate exposure to cold weather, thereby attributing climate change as the cause of their extinction; invalidating Martin’s
Once they are in the past and see the Tyrannosaurus Ray Bradbury uses imagery to explain what the dinosaur looks like. The Tyrannosaurus was described as, “...thirty feet above half the trees, a great evil of god, folding its delicate watchmaker’s
Title Researchers and scientists have constructed extensive research on dinosaur’s extinction. Speculation instead of real evidence seems common in most theories about the dinosaurs’ extinction. However, Jay Gould’s essay “Sex, Drugs, and the Extinction of Dinosaurs” is the complete opposite of speculation over evidence. Rather, Gould uses the mix of persuasive techniques, such as rhetorical questions, logos, along with profound evidence to not only disapprove of other theories but convince readers of his place on the dinosaur’s extinction.
Nancy Lord’s Early Warming and Elizabeth Kolbert’s “The Darkening Sea” both discuss how global warming is affecting the world. Lord and Kolbert talk about the negative result of climate change and try to raise awareness to global warming. Both Lord’s Early Warming and Kolbert’s “The Darkening Sea” use many different kinds of rhetorical strategies throughout their text. In Lord’s Early Warming, Lords relates to the community about climate change and tells stories about how global warming has affected many people around us.
In past research, there were people who do work about dinosaurs and the extinction. Mentioning in her book about Luis Alvarez and Walter Alvarez giving credit on their findings on the K-T extinction. Randall states,” Perhaps that was a good thing in that its inadequacy precipitated the search for another method by the geologist Walter Alvarez and his father, the physicist Luis Alvarez, which led to the meteoroid hypothesis,”(page 174, Randall). This gives explanation towards the reason in why she got into this project try to make a clear explanation about the Alvarez's work in their hypothesis. She recognized the meaning towards these two men in how they came up with the hypothesis.
Introduction For the review of Jurassic Park, by Michael Crichton, there will be a focus on the most prominent dinosaurs and their behavior. First the description of how the dinosaurs were depicted within the novel, followed by how their behaviors were accurate, or inaccurate, when compared to the fossil evidence that has been found around the dinosaurs. Velociraptor The depiction of the velociraptor in the novel is more accurate to the real-world dinosaur than the movie would depict. Velociraptors were depicted in a way that used scientific knowledge at the time of writing and some speculative elements for dramatic effect. Michael Crichton was fairly accurate at the time when the novel was released.
The author begins the poem with simple insights with the intentions of expanding the reader’s minds to see the true interpretation behind the strong use of metaphors “It could be the name of a prehistoric beast,” (Collins 1). Clearly the author doesn’t want or expect the reader top take the title Thesaurus, as some species of dinosaur. “Rising on its hind legs to show off its large vocabulary,” (Collins 3). The speaker uses the title itself as a make-believe synonym being theoretical dinosaur presenting its vocab; not words, but its actual structure. Shortly after those misleading metaphors, the author moves to the claim that is intended for the readers to understand.
TITLE “Sue” is one of the biggest and most complete T-rex skeleton ever found (text book pg. 140). If this skeleton would’ve been lost to illegal fossil trade dealers, then scientists and paleontologists would have also lost valuable evidence. Fossils are dead organisms that are buried by sediment that hardens, and then preserves the form of the dead organism (text book pg. 141). Fossils help provide evidence of the earth’s past and its developments (article 5 paragraph 4).
In this set of materials, the reading passage claims that the T-rex dinosaur has the remaining of the blood vessels, blood and collagen and provides three reasons of support. Whereas, in the lecture, the professor opposes the reading passage and says the evidences are skeptic. Also, he refutes each of the author’s reasons. First of all, the reading passage contends that the hollows in the T-rex’s bone are branching channels of the blood vessels. They contain flexible soft organic matter .
Although humans have contributed largely to the evolution of the world in a positive way, they have also deteriorated the world specifically through the abundance of fossil fuels used. These fossil fuels have contributed to many downfalls regarding our planet, one principal problem being global warming. In this essay, I will endeavor to obtain a potential resolution to the continuous debate that is ‘Did humans cause megafauna to become extinct?’. The first possible way humans may have beed responsible for the overall extinction of megafauna is through overkill, this is the hypothesis that humans drove many species of megafauna to extinction through excessive hunting.
Ray Bradbury used figurative language to describe the Tyrannosaurus Rex in “A Sound of Thunder. ’’ Ray Bradbury compared the legs to pistons, this means that the Tyrannosaurus Rex has strong legs. He compared it’s eyes to ostrich eggs, this means that the dinosaur has big eyes. He also compared muscles to thick ropes, this means that the dino has big thighs.
Document A states, "Climate change is warming the Arctic along with the rest of the planet — and in the Arctic, that means sea ice is melting," (DA) This is important for many reasons. Document A claims, "Sea ice is crucial for polar bears survival," and that "Most scientists agree that these trends spell likely trouble for polar bears. " This shows that the Arctic melting impacts polar bears and other Arctic animals, but that is not the only reason the artic melting is bad. The Arctic ice melts into water and Document H shows that millions of people all around the world would be flooded out of their homes.
