While the climate change theory offers a lot of evidence there a counter-argument exists. People wonder why a large climate change caused some animals to die out, but not all of them. Nobody knows for sure but scientists and paleontologists still look for answers to why some organisms were affected and some were not (“Dinosaur Extinction Theories”).

- 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.... [tags: asteroid, climate change, food]

- Extinction of Dinosaurs 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....

- Theories of the Extinctions of the Dionsaurs: Dinosaurs became extincted 65 million years ago, at the end of the Cretaceous period, something so devastating that it altered the course of life on earth. It seems like it happened so sudden, as geologic time goes, that almost all the dinosaurs living on earth disappeared. So how did these dominant creatures just die off. Was it a slow extinction, or did it happen all of the sudden. These questions bring rise to many different beliefs on how the dinosaur disappeared over 65 million years ago....

- Theories of the Extinction of the Dinosaurs Controversy surrounds the extinction of the dinosaurs. According to one theory, dinosaurs were slowly driven to extinction by environmental changes linked to the creeping withdrawal of shallow seas from the continents at the end of the dinosaur era. Proponents of this theory propose that dinosaurs dwindled in number and variety over several million years. An opposing theory proposes that the impact of asteroid or comet caused catastrophic destruction of the environment, leading to the extinction of the dinosaurs.... [tags: Papers]

- The Role of Fungus in the Extinction of Dinosaurs The debate over what ultimately killed off the dinosaurs is an area of great interest to not only scientists, but everyone. The dominant thought seems to be that an asteroid struck the earth at the end of the Cretaceous period and killed off much of the fauna and flora inhabiting the earth. However, the sequence of events following that mass extinction has been fairly blurry until a recent discovery, published in a recent issue of Science, by paleontologists Vivi Vajda and Stephen McLoughlin....

- Hypotheses on the Extinction of Dinosaurs In the early nineteen hundreds, dinosaur fossils were discovered and recognized around the globe. Greedy scientists and civilians, searching for their own prize skeleton, rushed to rip bones out of the ground, destroying the fossils as they went. It was not until later in the century that scientists and paleontologists began pondering how such widespread creatures disappeared. Currently, paleontologists debate the two main hypotheses of how the classic dinosaurs died: from volcanic activity or an asteroid impact.... [tags: Exploratory Essays Research Papers]

- Could an exploding star have been responsible for the death of the dinosaurs. This idea has become popular again as an explanation for the disappearance of the dinosaurs. An exploding star can blast material enormous distances into space. If this material reached Earth’s atmosphere, changes may have occurred that were harmful to life. We call an exploding star a supernova. Nova is the Latin word for new, and in ancient times, when an exploding star was observed, people often thought a new star was being born....

- So what killed the dinosaurs. Without having any background education in science it is hard for the general public to comprehend such matters and they rely on the knowledge of the scientists in this field. Although there has been much research on the subject nobody has come up with a conclusive answer. And we are left to read the countless articles, all having their own opinions as to the mass extinction. One such theory is that a shift in the solar system could have caused the mass destruction....

- Extinction of Dinosaurs due to Asteroid Impact Nobody knows for sure exactly how the dinosaurs became extinct. However scientists have speculated for decades about possible events that caused the dinosaurs to die out. Possibilities range from asteroids, to volcanoes, to climate changes. One of the more popular or well-known extinction theories involves the belief that an asteroid struck the Earth, causing devastating effects, and triggering mass extinctions around the end of the Cretaceous period....

- “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....
