What do we know about dinosaurs?

Слайд 2

There are a lot of myths about dinosaurs. Scientists discovered that dinosaurs died because of a great meteor , but there are a many versions how they could die. There could be a huge epedimic and all of the dinosaurs died. Velociraptor is one of the most popular dinosaurs from films. In reality he is very small and not dangerous at all. Scientists discovered that velociraptors had plumage. But not all the facts are true. We can’t look in the past and see what was happening. Myth and reality

Слайд 3

There is one most logically version , it was discovered in 1980 year by Luis Alvarez. - A huge meteor fell down on the Earth in the end of the Cretaceous period , but there aren’t enough evidences. There is a version about active volcanism. In one period a lot of volcanoes began to erupt. So all dinosaurs died too. There is one not important version – fighting with mammals. Big , slowly dinosaurs couldn’t fight to fast and deft mammals. So lot’s of big lizzards died. Why did dinosaurs die?

Слайд 11

If dinosaurs didn’t extinct , they would continue evolving and would turn into something between a man and a dinosaur. They would become clever , began evolving process like people had. And there would be no people on the Earth . What could happen if dinosaurs didn’t extinct?

Слайд 12

Lot’s of big dinosaurs extinct , but some small lizzards continued evolving. Some of dinosaurs with plumage , like Archaeopteryx stayed alive and continued evolving too. So birds that alive now long ago weren’t so small , they were v ery big , dangerous predators. There is a fact that some of the underwater dinosaurs alive. Some underwater dinosaurs who lived deep in the ocean , were safe from everything happened in atmosphere. So they would continue staying alive. There was one happening when some of the sailors saw shark bigger than their boat , they said it was a Megalodon . After that they didn’t work sailors anymore. Are there any dinosaur alive?
