Hypotheses on the Extinction of Dinosaurs

Hypothesis on extinction of dinosaurs In the early 19th century, dinosaur fossils were discovered and recognized around the world. Greed scientists and citizens seek out the skeleton of their awards, rush to the ground to tear the bones and destroy fossils. It was not until the end of the century that scientists and paleontologists began to think about how such extensive creatures disappeared. Currently, paleontologists discuss two major assumptions about how classic dinosaurs die: volcanism activity or impact of asteroids.

Scientists believe that the extinction of dinosaurs and many other biota in the late Cretaceous years, 65.5 million years ago, is attributable to one or more catastrophic events, including the influence of at least one asteroid (especially those that produced the Tikszrol valble) I guess it was caused by an event. Or it may increase volcanic activity. Images provided by NASA and Wikipedia. Likewise, principle (c) does not meet the purpose. We can not achieve our initial goal. Because it severely narrows the scope of science and severely limits the scope of many historical sciences that often exclude all single events from that area and therefore must often deal with unusual events. Events, or events that are no longer replicable today. Not only a number of "original" events (such as the origins of the universe and the life on Earth) but also the one-time radioactivity that occurred in the past (eg,

Since the discovery of the first fossil paleontologist and other scientists, people are wondering where the dinosaur disappeared. When will the dinosaurs disappear? How are they extinct? I have asked these questions for many years. However, there are two different aspects to these theories. Scientific theory and religious theory Both have very good ideas and very interesting views

The theory of dinosaur extinction develops mainly on the extinction of dinosaurs. According to a theory, at the end of the dinosaur era, the environmental change associated with the progressive withdrawal of the shallow ocean of the continent brought the dinosaur out of extinction. Supporters of the theory suggest that the number and type of dinosaurs will gradually decrease after millions of years.
