Recommended: Disappearance of dinosaurs
In Theory, there a infinitely many possibilities of what really happened to the dinosaurs. Every scientist, and every religious group say they have an idea of what really happened. But how can we tell whether they are wrong or right? We can’t. We can only make a guess, or believe what we want to believe. Religious people have their beliefs and the scientist have their beliefs too. We, ourselves have to decide on which ones we want to believe.
Scientists have had many theories for what happened to the dinosaurs. Like a big meteor crashed into the ground and killed a bunch of them: then the plants died, causing the herbivore’s to die; then when the herbivores died with the carnivores following after them. “One of the most common extinction theories is that an asteroid 4-9 miles (10 km) wide struck the earth on the tip of the Yucatan Peninsula, in the Gulf of Mexico dealing the dinosaurs a fatal blow.” Or scientists say that they all have evolved into birds. The scientist also think maybe diseases might have killed of the dinosaurs. Scientists say that as the Cretaceous period went on more and more land bridges were appearing. So the oceans were drying, and dinosaurs were able to walk across land they used to not be able to walk on. As the dinosaurs walked across these land bridges, looking for food, they would find ancestors from when the world was one. Now with the land bridges, there was more than dinosaurs going across these land bridges. The dinosaurs walking across brought the diseases they had inside them with them. They were immune to the diseases they had, bought the other dinosaurs they find weren't. So they all passed diseases to each other and possibly killed each other. “In most cases disease in a species is not...

...rrors in the bible. Yes that ticks people off (especially me) but we can’t say for sure. Maybe it’s our fault for being hindered with the ability to argue, and not believe things without proof. Maybe we need to change our ways. But is that going to happen? So until that time when some sort of event reveals us the answer, we will never be for sure.

Michael Crichton’s classic novel Jurassic Park sparked controversy among scientists, excited science-fiction fans, and captivated paleontologists as Chrichton proposed the idea that dinosaurs could be cloned. The plot elicited criticism from scientists around the world, but support from others. Cloning a dinosaur was made possible in the fictional text: take some amber, fill in missing DNA, obtain an ostrich egg, keep the egg in a controlled environment, then a dinosaur is born. Unfortunately, each of the steps are of intricate design.
“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.
...at people say even though when it is not true because we tends to believe what others says. Our memories in our mind can be tricky and get mixed up by what people say; it can trick us in to believing that it is true. In which that makes them unable to separate what is fake, fantasy, from reality.
...ories of why dinosaurs went extinct abound, and as there is no theory yet to be truly confirmed as the “right one”, my theory of dinosaur cannibalism is also purely anecdotal. The discovery of the cannibalistic Majungatholus atopus in Madagascar is an important scientific find because it confirms a long-standing theory of cannibalism among certain carnivorous dinosaurs. Behavioral patterns of extinct animals are difficult to establish; however, these bones give authentication to previous unfounded beliefs about the ancient feeding practices of some dinosaurs.
Although we can only do so much with DNA and protein fragments, they are still discoveries, which are going against previous intuitions. Again, no cloning of dinosaurs are going to take place any time soon, but DNA may help to link dinosaurs with other species around today. These two articles, the research article and the review article show strong evidence that preserved proteins, including DNA can survive under the perfect circumstances. Of course more research will need to be done, and hopefully more findings will conclude the same results.
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. According to an article published in Nature magazine,

We use dinosaurs to represent the changes in nature that have occurred throughout time. Studies found that although the “oldest rock did not show evidence of life, the progression of plant and animal life that changed in recognizable intervals, from ancient life, age of reptiles to the age of mammals” (Dino Nature Metaphor, slide 6), measured the age of the earth. When we think of dinosaurs in relation to nature, we think of that very powerful force that controls the cycle of life. Nature was able to yield such magnificent ferocious creatures that walked the earth and then take them back when they served nature’s purpose. Dinosaurs fit perfectly in nature’s constant
There has been a debate about what happened to the dinosaurs since they were discovered. There are many thoughts of what happened to the dinosaurs, the two main theories behind the extinction are scientific and religious. Proof for both theories do exist and debates between scientists are still going on to which one really happened. It is a mystery as much for Evolutionists as it is for Creationists about the extinction of the dinosaurs. The fossil record of dinosaurs was poorly know for a long period of time. During this time period was when the dinosaurs were thought to have gone extinct. The scientific reason for their extinction was that there was a giant asteroid that caused chain reaction and wiped out the dinosaurs. Some scientists say the dinosaur’s extinction came quickly. Evolutionists say the dinosaurs went extinct 65 million years ago. Creationists say that the dinosaurs weren’t able to survive the Earth after the flood. Both of the theories have supporting evidence and that is why there is an ongoing debate over what really happened to the dinosaurs. (WGBH Educational Foundation and Clear Blue Sky Productions, Inc. et al., 2001)
No one knows for certain exactly why and how the dinosaurs became extinct. Probably the most popular theory right now is the Asteroid Theory. According to this theory a large asteroid or comet collided with Earth about 65 million years ago. Scientists think that such a large collision would throw so much dust into the air that sunlight would not be able to shine and plants and animals would die.
Throughout Earth’s history there have been many changes. These changes have consisted of temperature fluctuations, atmospheric differentiations, extinctions of various plant and animal life, etc. Over time everything seems to have evolved in some way form or fashion. However, the Permian Era extinction was different from all the rest. This extinction affected every form of life, but especially the marine life. Researchers have stated that 93-97% of all Earths species went extinct during this period of time. This essay will explain how a once blossoming progressive era turned into Earths most catastrophic event.
seems like it happened so sudden, as geologic time goes, that almost all the dinosaurs
Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant.
The asteroid was approximately 6 miles across and it caused a lot of changes that affected the dinosaurs. Some of these were temperature changes, acid rain, air borne debris, regional wildfires, and months or even years of darkness. The resulting plume of the debris from the asteroid impact could have caused the sun to become temporarily blocked. Therefore, this could have caused the plants to die, causing the herbivores that ate them to die, resulting in the carnivores also dying. (J. David Archibald, 1034)
