The extinction of the dinosaurs is one of the most well-known mysteries in our great world, the Earth has its history in the layers, these layers can tell us when, where, and how something happened, the K-T boundary is no exception. These large slabs of Earth can show us the past, millions of years of history, to the beginning. What scientists around the world are trying to figure out, is why the dinosaurs died out, there are many different and unique theories about the K-T extinction. Some theories have good evidence, others have little to none, but there are no guarantees if the evidence is actually good enough. Many people believe that the great extinction happened because of the impact of a cosmic asteroid and created a massive explosion

There is, however, some things that give clues as to which occurrences is the culprit to this famous extinction. There is a layer of iridium, a rare metal found in space rocks, in the layer which dates back to the K-T boundary (PBS); this layer is evidence that unless the volcanic reactions put up that much iridium, there was an extraterrestrial body that hit earth and caused a layer of iridium-rich rock to form. The other mass extinctions have evidence that climate change was the reason for the extinction, including the Great Dying, the largest mass extinction recorded. There are ancient volcanic layers also found in the K-T boundary layer, so there were also hints of a volcanic climate disruption, causing the surface to cool down, this would cause a wide spread change in populations, the dinosaurs wouldn’t be able to stand the cold, and would perish. What about the other animals that went extinct, if global cooling didn’t harm them, then what did? There would have to be some unnatural occurrence that would have killed off the rest of the animals that went extinct, so that is why the hybrid theory exists. Still, there are some who think there is only one sole cause for this massive dinosaur …show more content…
In India, there are records of ancient volcanic activity that occurred at the time of the K-T boundary. Aside from the iridium layer of rock that gives evidence to an impact, there is also a 110-mile crater found in the Yucatan peninsula that also dates back to the time of the dinosaurs’ extinction point, and at that crater; there are no non-avian dinosaurs that were found at the impact layer, so that also gives evidence that something was causing the dinosaurs to die before the meteorite struck. What about the other theories, are they plausible too? No they are not. If the dinosaurs’ brains were too big for their bodies, then how come they live for millions of years? If the plants died out first, then how come the dinosaurs died out at the same time the plants went extinct? There is just no other reasonable explanation but the hybrid theory; it’s the most accurate, and the most fully plausible explanation for the cause of the death of the
