Watch in a different language
Hello Friends and welcome to a new happy learning video. Today we are going to talk about some animals that existed 65 million years ago. I am sure you have heard about the dinosaurs, and I am certain you have seen many films and cartoons featuring dinosaurs. But…not everything that is told in these films is correct. So, if you don’t mind, let’s find out what they really were like and how they lived.
The first thing we need to understand is that people and dinosaurs never lived together.
The dinosaurs lived before human beings existed and they roamed the Earth for approximately 135 million years. That’s a really long time! They were the dominating vertebrates. Nowadays more than 500 different species have been identified thanks to bones and fossils found.
All dinosaurs were oviparous, meaning they reproduced by laying eggs but there were huge differences between them; some were very small while others were absolutely enormous…
So as to learn about them better, we have divided them into two major groups:
The Ornithischia and the Saurischia. What complicated names they have!
The Ornithischia or “bird-hipped” dinosaurs were herbivore, which means they only ate plants. The most well-known was the Triceratops. They were impressive, huh?
The Saurischia or “lizard hipped” dinosaurs are the ancestors of the crocodiles and lizards. Among this species there were carnivores and herbivores and within them the two most famous dinosaurs, the
diplodocus and the tyrannosaurus.
The diplodocus was the largest dinosaur. In 1907 an entire skeleton was found measuring 27 meters, although remains of these specimens have been found exceeding 50 meters. In these images you can observe just how enormous they were…
The Tyrannosaurus was and still is the most fearsome predator which has ever existed on our Planet. It was more than 4 metres high and could be up to 12 meters in length. In its mouth it had 60 razor sharp pointed teeth, and it could run…65 kms per hour!!! The truth is I would be absolutely petrified if I were to come across such an animal…
But wait a minute, how is it possible that such large and powerful animals completely disappeared off the face of the Earth?
Currently, the investigators are focusing on two big theories: the first is based on the impact of an asteroid or comet from outer space. The other theory maintains that the cause of the dinosaurs’ disappearance was due to a period of enormous volcanic activity. We actually still don’t truly know the reason. But what we do know with absolute certainty is that, right now, at this very moment there are still many animals in great danger of becoming extinct, and could even disappear. All of us can help them survive. How? By respecting nature, recycling, contaminating the least bit possible, buying only what we really need…If we make these efforts we will be able to live in a much healthier planet and we will at the same time be ensuring that no animal, not a single one, will ever be in danger of extinction again. Let’s hope with everybody’s help, we can make it happen.
