Dinosaurs Are Endotherms Summary

While the author of the article believes that Brachiosaurus were aquatic animals, the professor disagrees with this statement. The professor points out that in spite of the fact that some species of dinosaur would spend a great deal of time in water, there was no possible that Brachiosaurus were aquatic ones. To strengthen her point, the professor provides sufficient evidence respectively to the points made in the article.

The reading passage proposes three theories which support the idea that a dinosaur which is called edmontosaurus survived in the winter by migrating to the south, the more hospitable region than the extremely cold in the North Slope. However, the professor in the listening respectively contradicts each theory in the reading passage by using strong evidence as support.

At first, the reading passage posits that the diet for these dinosaurs proves that they had to migrate to find plants. Conversely, the professor refutes this point by imparting that this ratiocination is invalid on the ground that there was in some period a warm climate in this area. According to the professor, the 24 hours sunshine eventuated in warm weather and extensive daylight would provide a desirable environment

The reading and the lecture are both theories of why dinasours were endotherms or cold blooded aninmals. Whereas as the author of the reading states that there is not enough evidence to assume that dinosaurs were endotherms. The lecture casts doubt on the main points made in the reading by providing three reasons.

First of all, the passage states that the special kind of dinosaurs , Edmonstosaurus, had to migrate because of finding food to survive, But on the other hand the professor states that in that period of time the weather exchanges were not notable as they are today, and whether the seasons change the vegetation amount didn't vary a lot. Also she noted that even if the vegetables were hard to find in winter, there would be other nutrition available.

First, the argument stated in the article readily assumes that dinasours fossils are located in the polar regions and this is the evidence to determine that dinasours were endhoterm. In contrast, the professor provides information that these polar regions were much warmer than today. In addition, she states that when the climate was so cold in these regions, dinasours were migrating or hibernating. That’s why we can not easily assume that dinasours were endhoterms.

who theorize that volcanic eruptions could have been the cause for the extinction of dinosaurs

Dinosaurs ruled the earth for over 65 million years and thankfully for the human race, they became extinct. Ultimately, only a major catastrophe could completely wipe out an entire species, let alone an entity of dinosaurs and the debacle on the causes of dinosaur extinction have flooded the minds of paleontologists for centuries. Geologist and zoologist Stephen Jay Gould published “Sex, Drugs, Disasters, and the Extinction of Dinosaurs,” to compare scientific and speculative causes of dinosaur decimation. Personally, I found this passage very informational and enjoyed reading it. Gould provides three theories that capture the reader’s curiosity, allowing room for pondering in one’s mind.

            At a time, scientists believed all dinosaurs were cold-blooded.  However, with a recent discovery of a dinosaur found with a fossilized heart in the northern part of South Dakota in 1993, many paleontologists are starting to think that there were some dinosaurs that were warm blooded.

Throughout the scientific article there are many examples of factors that decrease the reliability of the article ‘did humans and dinosaurs co-exist’? Dr Manfred E. Kober has no degree or speciality in the evolution of Homo Genus, instead he specialises in theology with Th.M. and Th.D. degrees. This subsequently lowers his reliability as a source because he is a Theologist who believes in the theory of creation. His views may present bias as he is from the perspective that evolution does not exist – such beliefs go against the mainstream scientific views commonly accepted today. He also states that Homo Habilis and Homo erectus “Lived side by side about 1.5 million years ago in parts of Kenya’. There is no evidence that Homo Habilis

Jurassic Park by Michael Crichton demonstrated many dinosaur characteristics and behaviors. The dinosaurs were fictionally characterized to appeal to the readers. By examining the dinosaur’s appearance and behaviors of dinosaurs such as the duckbilled dinosaur, velociraptor, hypsilophodontids, dilophosaurs, Triceratops, apatosaurs, Tyrannosaurus rex, stegosaurs, and maiasaurs distinguished whether the evidence existed in the field of paleontology. The behaviors and characteristics of the dinosaur are divided into three factors as behaviors that were supported, not supported, and no evidence to support or refute the behavior.

First, according to the reading passage dinosaurs fossils were found in Polar Regions, which means that dinosaurs can maintain their body temperature higher than such cold temperature, and so only endotherms animals have this characteristic. The lecturer, on the other hand, contradicts this point of view. the lecturer mentions that polar regions were warmer than they are now. In addition, when the weather was cold sometimes, dinosaurs used to migrate to warmer areas or hibernate. Therefore, this evidence

This researcher proposes that the dinosaurs did not die of heat, in fact she thinks the opposite, that they froze to death instead. Both articles have the same idea about a meteorite hitting the earth yet there is no concrete evidence as to what caused the meteorite to strike and what it did when it got here.

The passage points that dinosaur fossils have been found in polar area where is very cold and merely endotherms could live there. However, the professor explains that these days Polar Regions are much colder than used to be. Therefore, this claim could not prove the author's idea.

Rapid climate change also ends up on the suspect list of possible dinosaur extinction events. During the latter part of the Cretaceous Period continents broke up causing volcanoes to erupt and fill the sky with gas and ash resulting in a drastic climate change (“Dinosaurs Climate Change and Biodiversity”). The shifting of continents changed the Earth’s landscape, altering weather patterns and overall climate (“Dinosaur Extinction Theories”). Also, over a long period of time, climate gradually changed. Ocean habits changed, temperatures grew much more extreme causing scorching summers and frigid winters (Norell, Dingus, and Gaffney). Radical temperature changes like these led to a green-house effect, making life for the dinosaurs a lot
