There are many theories, but no one knows for sure. Some scientists believe massive climate changes, such as extreme heat or extreme cold cause the dinosaurs to die out. The most popular reason, however, is the meteor theory. A great number of a scientists say that a giant meteor struck the Earth during the dinosaur ages, and wiped them all out. The crash supposedly threw so much dust and ash into the air, it took a very long time to settle. The particles in the air blocked a significant amount of sunlight to Earth. Because of this, many plants died which, in turn, caused a catastrophic affect on the herbivore dinosaurs and then the carnivores and omnivores. They say that the meteor that caused the extinction of the dinosaurs caused the Chicxulub Crater in Mexico. This theory is so popular because it is supported most by geographical evidence. However, it is still not supported by enough evidence to say that this theory is 100% what happened. I, personally, do not think they will ever solve the dinosaur extinction mystery. Hope this helps!

∙ 13y agoScientists are not sure what caused the extinction of the mammoths and other megafaunal mammals, but they do have a few theories. One is climate change at the end of the Ice Age. The other two include human induced diseases, humans overhunting the megafaunal mammals, or any combination of the above.
