10 Dinosaur facts

Geologists have found earths weirdest and some of the biggest animals that use to roam on this very place where we live today, millions of years ago. All the ancient cave paintings and those found on pots show only those animals that we know and see even today. So we cannot be sure to say that dinosaurs lived with humans. Dinosaurs are usually considered to be weird, powerful and dangerous animals but not all of them were like this. Below are given some facts about dinosaurs.

1. Before Dinosaurs

Many people think that before dinosaurs there was nothing on planet earth. Dinosaurs appeared on earth 200 million years ago, their era is called Jurassic park. Before this, there were archosaurs on earth. Before archosaurs, or big lizards, there was mammal like reptiles.

2. The Undiscovered

There are still many types and classes of dinosaurs to be discovered yet. The fossils found by the geologists are only 150 million years old or 80 to 65 years old. There are still much more to be found because fossils are a rare process and not every dinosaur left its fossils.

3. The Deep Times

In geology terms, deep times mean the long period of time a race can survive. Human race can be found only by a time track of 10,000 or so years, but dinosaurs lived for 150 million years and they are called most successful colonizers.

4. Most Dangerous In Dino Time

Some species of dinosaurs were indeed dangerous and blood thirsty but at the time they appeared on earth, the most dangerous species were crocodiles.

5. Groups

There are two groups of dinosaurs called, saurischain and ornithischain. The saurischain were the herbivors and they are called lizard-hipped. The ornithischain are called the bird-hipped. The birds of today have evolved from saurischain.

6. Modern Day Birds

There is a big group of paleontologists who think that the modern day birds evolved from the feathered dinosaurs. But not everyone agrees.

7. Cooled Blooded

It is said that dinosaurs were cold blooded like the today’s crocodiles and turtles. But then it is also believed and argued that those carnivores that lived an active life must have been warm blooded.

8. Herbivores

The balance of the ecosystem says that herbivores are always more in number then carnivores. Carnivores make only a small portion of total animal population. Same is with the dinosaur population, most of them were herbivores

9. Dumb

Most dinosaurs had very tiny brains compared to their body. These brains only had the information regarding their average and usual life, stored. The predators had relatively smarter approach towards life.

10. Movies

Dinosaurs have been given enough coverage. Not only expensive documentaries have been filmed but also some expensive Hollywood movies have been directed on them. The Jurassic park is one such example.
