The Cause of the Dinosaur Extinction

The extinction of dinosaurs is because the greatest mystery surrounding dinosaurs is their way of death. A dinosaur of over 130 million years dominates the earth. Then 65 million years ago, at the end of the Cretaceous, they became extinct. Everyone has their own idea, but nobody really can say that this species was actually eliminated. Influence of asteroids, atmospheric change (from high temperature to low temperature), devastating occurrence, and astronomical events (such as supernovae). Some people adventured that early mammalian habitat would slowly annihilate dinosaurs.

6:24 am on December 30: The figure shows that a huge meteorite and several small meteorites are flying in the sky. This is the reason why so-called dinosaurs are extinct, evolutionists can go back to the 65 Ma's K-Pg boundary. However, if the dinosaur is too old, you can not expect blood vessels, blood cells, proteins, DNA, 14 C to appear in the dinosaur bones, but that is the case (see the dinosaur 's 20 - year uneasiness desperate Evolutionists put irons to protect millions of years of ideas

what is that? Scientists can not be 100% convinced of events that have caused dinosaur extinction. Students learn various kinds of dinosaurs and their habitats. To describe what happened to the dinosaurs, the students will conduct additional research on the annihilation of the dinosaurs. Students also introduce their research and create a museum to share with others.

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. "Suddenly, it was a small pea, a beautiful blue, the earth that shocked me suddenly, I set my thumbs, closed my eyes, my thumb dirtied the earth, like I was a giant I do not feel I am Neil Armstrong said that this is his famous trip, he was the first man on the moon, one of several people with opportunity. Earth has always been the residence of mankind since.

Over the years many thoughts have been spread about the cause of the extinction of dinosaurs at the end of Cretaceous. This is an interesting mystery for many years, as the dinosaurs have such a strong footing on the earth. It seems surprising that these multipurpose creatures may have been canceled by one thing. To achieve a permanent goal, you must be a really big person. Several ideas that may explain the final extinction of the Cretaceous have been proposed and rejected, but at least two still exist. The evidence supporting the influence of asteroids is convincing. The idea of ​​a huge asteroid affecting the removal of dinosaurs began with the discovery of thin layers of rocks in the world's layers. This layer dates back to about 66 million years ago (the duration of this event), it spreads throughout the earth and is abundant in cesium.
