During the course of history, two theories have evolved that explain what happened to the dinosaurs. These two theories have been debated back and forth between evolutionists and religious followers. Evolutionists believe that dinosaurs became the most powerful beings on Earth around 235 million years ago. They believe that no humans existed at the time. Evolutionist views also say that all the dinosaurs were killed by a cataclysmic event.
The asteroid was so large and landed with such force that it effectively ended the dinosaurs reign over the earth. However, recent evidence and research reported in Proceedings of the National Academy of Sciences suggests that this could not have been the case, because the Chicxulab crater predates the mass extinction by roughly 300,000 years. Rather, the evidence suggests that two or more impacts caused the mass extinction experienced by dinosaurs. Fossil records inform us that the mass extinction occurred 65 million years ago. This landmark coincides with and marks the Cretaceous-Tertiary (K-T) boundary.
How dinosaurs went extinct? Seeing as how people always have their eye on the future it’s hard to know our past, for an example with dinosaurs. What exactly happened to them is a mystery; we know that they are extinct but how exactly. There are many types of theories out there like the Asteroid Impact theory, the possibility of the climate changing, and the thought out volcano eruption idea but which of these is accurate. There is more proof to support the impact theory overall and is highly considered to be more accurate among most scientists.
Ever since paleontologist have found dinosaurs there has been a debate on how these incredible creatures died. This big debate is between the scientific theory and the religious theory of how the dinosaurs had died off. The science side of the debate think it was a comet or asteroid crashed into earth killing them off, just like we are told in school growing up. Then of course you have the religious side of the debate, which we are not taught about in school, and they think that the dinosaurs were killed off by the great flood in the Bible when Noah made the Ark. Of course neither side is for sure correct but, both sides do both make very good points that should be considered.
The Cause of the Dinosaur Extinction The biggest mystery surrounding the dinosaur is how did they die? For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out. Nobody can really say what actually eliminated the species, although everyone has their very own idea. Asteroid impact, atmospheric changes (hot to cold), catastrophic eruptions and astronomical events (supernovas etc.).
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. The last theory that dinosaurs died due to a large amount of volcanism comes up in scientists list of theories as well. Many different theories of why dinosaurs went extinct include extinction by asteroid, mammals outcompeting dinosaurs, climate change and volcanism. The most popular theory of dinosaur extinction, the asteroid theory, says that dinosaurs died out because of a single, giant asteroid.
The religious view points toward Adams sin being the reason the dinosaurs were wiped out. The scientific point of view is that there was a cataclysmic asteroid impact that made them go extinct. Both are similar because the dinosaurs were wiped out either way. Scientists often think at times that the existence of dinosaurs and their demise is so shrouded in mystery, that people will never know what happened to them. According to Scientists dinosaurs first evolved around 235 million years ago, way before man evolved.
Scientists believe that the dinosaurs came to a quick and catastrophic end. With months of research scientists found out, dense clouds blocked the sun's rays darkening and chilling the earth to deadly temperatures. Then settled greenhouse gasses caused by impact caused temperatures to skyrocket above normal levels. In a few years, according to this hypothesis, these temperatures caused not just dinosaurs but 70% of plant and animal life to come to a dramatic end.

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. The asteroid impact extinction theory began in 1980 with Luis and Walter Alvarez, a father and son team.
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.
