The Extinction of Dinosaurs How did the dinosaurs become extinct? This is a question that has stumped scientists ever since dinosaur fossils were first discovered. There are many theories as to how the dinosaurs became extinct. This page presents some of the most popular theories. Keep in mind that there is no absolutely proven theory.
Dinosaurs are no longer with us. We often overlook the reason they are not here or why they became so extinct. According to the asteroid theory a large collision between earth and an asteroid threw up so much dust into the air that it made it impossible for sunlight to get to earth. This was said to been happened sixty-five years ago during the Mesozoic era. Being that there was not enough sun light it made it impossible for plants and animals to survive.
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. Although they result in the same outcome, the volcanic and asteroid hypotheses differ in key elements: the actual event, the environment's stress, and the impact on life.
What were dinosaurs like? How did they survive? How did they become extinct? These are some of the many questions to which answers are being sought. Dinosaurs were one of the largest creatures to ever walk the earth and one of the mysterious creatures too, how they survived and how they became extinct in a flash has been a mystery.
Although it is believed that the asteroid theory is the cause of extinction of the Crustaceous Period, we cannot be positive. The environmental effects of this problem were that the dinosaurs living during this period perished from the earth and their extinction remains a mystery to us to this day. All we can do to reenact what happened is use the technology we have in the twenty first century to find more evidence to see what went wrong so long ago. By discovering things like what happened to the Tyrannosaurus Rex we can use this information to prevent an event such as a mass extinction from happening a second time. Although it is impossible to rewrite history, we still have to be careful to prevent a catastrophe like the asteroid said to have hit the earth sixty five million years ago.
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.
The theories of where the dino’s have gone has been a long mystery. Since the finding of the first fossil paleontologists and other scientists have long wondered where the dinosaurs have gone. When did the dinosaurs go extinct? How did they go extinct? All these questions have been asked for years.

One prominent flub that is witnessed throughout the duration of the film, besides the fact that most of the dinosaurs are from the cretaceous period, is the fact that it remains impossible to bring dinosaurs back to life. Dinosaurs are extinct! They have been extinct for 65 million years. True, one would need dinosaur DNA to recreate dinosaurs, and it is indeed possible for mosquitoes with the DNA of dinosaurs to have been trapped in hardening amber, as seen in the film. However, it is impossible for scientists today to find hardened amber with dinosaur DNA in it, simply because DNA does not last; it degrades over time (even in preserved amber).
The prominent theory is that dinosaurs died in a fiery death due to an asteroid crash on Earth, but is that really what caused their mass extinction? Every scientist has a theory, and with so many out there it was hard to just pick one, they all made sense. It is completely possible for a volcano to have killed the dinosaurs, or even an asteroid. Another popular theory was the ice age. These were all plausible reasons for the extinction of dinosaurs, and that’s when the combination theory was discovered.
