Why Did Dinosaurs Die Out

The biggest question about dinosaurs today is “How did they die?” “There is nothing like a bold new hypothesis to galvanize scientists into reaction and then action.”(Wilford, John Noble.) Many scientists have created new theories and hypothesize, some have been backed up with evidence while others are pure imagination. The first and most evidence backed theory is called the K-T event theory. This theory was created by a father and son duo Luis and Walter Alvarez. “In the 1980s, father-and-son scientists Luis (1911-88) and Walter Alvarez (1940-) discovered in the geological record a distinct layer of iridium–an element found in abundance only in space–that corresponds to the precise time the dinosaurs died. This suggests that a comet, asteroid or meteor impact event …show more content…
Other scientists believe that the dinosaurs were simply not smart enough to adapt to each other and survive. There were many scavenger dinosaurs who ate eggs. “Small mammals ate dinosaur eggs, thereby reducing the dinosaur population until it became unsustainable.” (History.com Staff. "Why Did the Dinosaurs Die Out?" History.com. A&E Television ) They believe that the scavengers ate all the offspring and they couldn’t reproduce fast enough so they eventually all died. This theory is a very hard one to prove and doesn’t follow along the lines of the dinosaurs extinction being sudden. It would have taken a very long time for this one to happen which is why it is probably the least believed theory, and has the least amount of evidence. The last major theory is that a volcano erupted spreading a layer of ash across the atmosphere and blocking the sun. The Earth became too cold for any of the dinosaurs to adapt and live thus causing them extinction. Many different scientists have different theories about how the dinosaurs died but none of them have enough truth to be exactly sure of which one is right, making them all just theories, and none of them
