The idea of the word dinosaur comes from the ancient Greek words deinos (terrible) and sauros (lizard).  And they can’t speak Strictly speaking dinosaurs refer to land dwelling creatures that dominated life on earth during the Mesozoic Era (225 million to 65 million years ago).And it was pangea . They lived alongside with marine reptiles (such as ichthyosaurs, mosasaurs, plesiosaurs). And there are more different tide  of dinosaur . As a group, dinosaurs existed for over 150 million years occupying every type of environment and climate on Earth. They ranged in size from those as small as a chicken to others over 100 feet long and weighing nearly 100 tons. Dinosaurs did not achieve their great size or domination overnight – they evolved alongside reptiles and mammals but managed to outcompete them. Were it not for the great Cretaceous extinction 65 million years ago the mammals would not have evolved as they did nor would human beings as we know them exist.  This is the idea of it

  The main idea and evidence no. dinosaur are a group of ancient reptiles that had a set of particular skeletal features. The hips hind legs and ankles were specialized and allowed the legs to move directly under the body rather than extending out from the side of the body as in modern lizards. This arrangement enabled dinosaurs to bring their knees and ankles directly below their hips and provided the necessary attachments for very strong leg muscles. Dinosaur skeletons were well designed for supporting a large body for standing erect (upright) and for running. The front legs were adapted for grasping prey for supporting weight or for walking and running. The skulls of dinosaurs were designed for maximum strength for minimum weight and (in some cases) for grasping holding or tearing at prey. These skeletal features separated dinosaurs from other ancient reptiles such as Dimetrodon the plesiosaurs and pterosaurs. Fossil mammals like mammoths and saber-toothed tigers (e.g., Smilodon) are also often incorrectly called dinosaurs.

Of course, no human being has ever seen a living dinosaur. The dinosaurs had been extinct for about 65 million years before humans appeared on Earth.

If no one has ever seen a dinosaur how do we know what they look like? Well scientists have found their fossilized bones  sometimes they have even found complete skeletons.

By studying dinosaur bones scientists have been able to reconstruct what they looked like how they moved even what they ate. Most of what we think we know about dinosaurs is the result of educated guesses based on comparing the dinosaur skeletons with modern animals.

What happened to the dinosaurs? For over a century, paleontologists have been puzzling over the fate of our favorite prehistoric oddities. The non-avian dinosaurs dominated the planet for an inconceivably long period of time, and their evolutionary success only heightens the mystery of their downfall

Dinosaur was the first thing walk the earth ;

Dinosaurs walked the earth for over 165 million years . And they are  different like some of them eat  grass and

The GYother eat meat and they eat each other tham bran

Was like coconut size it was small and they didn’t think

And they cannot speak and they didn’t live in a nice places

Some of them live in  Mesozoic Era , but not all dinosaur live in the same year or time the bad new when a dinosaur

Born in jurassic period they have a bad luck because

The METEOR AND METRORITES  came to earth and this is the END for

Dinosaur !!. and so the first time a scientist who find the first dinosaur is Richard Owen who is the first scientist

Find the dinosaur fossil and tear from it he called it geand  lizard .

And so did the volcano kill  the dinosaur yes and no the most part is METEOR AND METEORITES kill all of them . That sad !   

 I got all of these not from nation goph i get the idea from their .  

And some idea of the History of it .

This is all  the idea and some of them i gat theam

From the books.

Some videos of dinosaur history .

I wonder if the us can bring back back the dinosaur

And they are trying to bring back ice age animal

Like dodo bird and Mammoth and sabre tooth and some

Another anime
