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 more difficult (“Dinosaur Extinction Theories”). Changes in rainfall caused some places to suffer droughts and other places flooded, killing almost all the wildlife in affected areas (“Dinosaur Extinction Theory”). Around the middle part of the Cretaceous period a ten degree Celsius increase in average world temperature occurred (“Dinosaurs Climate Change and Biodiversity”). The climate change could’ve possibly happened over a long time span. Fossils show that woodland vegetation took the spot of tropical plants due to the Earth cooling. Perhaps dinosaurs could not adapt to this, resulting in their extinction.
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”).
Some experts say that dinosaurs died off b...

Theories of the Extinction of the Dinosaurs Essay

- 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]

Essay on The Role of Fungus in the Extinction of Dinosaurs

- 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....   [tags: Anthropology Essays Paleontology Papers]

Hypotheses on the Extinction of Dinosaurs Essays

- 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]

Extinction Of Dinosaurs Essay

- 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....   [tags: essays research papers]

Contrasting Theories on the Extinction of Dinosaurs Essay

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....   [tags: Compare Contrast]

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

- “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....   [tags: essays research papers]
