Amazing Facts About Dinosaurs that will Intrigue You (Part I)

There is no concrete answer to how they got suddenly extinct and there are many theories about it.

We all know that dinosaurs were really big animals and some of them had the ability to fly also and they ruled the earth for millions of years but went extinct 65 million years ago. The theory of the earth being hit by meteorites which made them extinct is the most accepted theory. Here we have created a list of a few amazing facts about Dinosaurs that will intrigue you.

There Were Huge Reptiles on Earth Before Dinosaurs. 

Most of us think that Dinosaurs were the only large reptiles on earth millions of years ago but there were other reptiles that lived on earth even before the evolution of Dinosaurs. 

The first dinosaurs evolved about 230 million years ago which is known as the late Triassic period. Most of us think that dinosaurs were the first large giants that walked on the earth but you will be surprised that before the dinosaurs, other large reptiles existed on the earth. The supercontinent of Pangea had land reptiles such as large-sized lizards known as archosaurs, mammal-like reptiles named therapsids and pelycosaurs, dimetrodon, etc. The most fearsome reptiles on Earth existed in the early Permian era which is about 295 million years ago from today. The Dinosaurs came into existence around 200 million years ago after most of the earlier reptiles became extinct.

Dinosaurs Existed for Nearly 150 Million Years

 Dinosaurs existed for about 150 million years making them the longest-living creatures on the earth.

Most of us know that Dinosaurs walked on earth for around 150 million years, perhaps the creatures which existed for the longest period of time. Humans existed for only 10,000 years which is merely a few blinks of the eyes of a dinosaur if we compare the period of existence of humans and dinosaurs. They became extinct nearly 65 million years ago and modern human beings came into existence only 10,000 years ago. Just thinking about them makes us amazed at how they existed for millions of years and suddenly got extinct a few million years ago.

Dinosaurs are Divided into Two Main Groups

Paleontologists (scientists who study the history of life on Earth through the fossil records)  and expert researchers on dinosaurs have divided them into two main groups apart from dividing them as carnivorous and herbivorous.

Paleontologists and research people who researched a lot about these giants and are specialists in dinosaurs have divided dinosaurs into two main groups.

You might be thinking it’s either carnivorous or herbivorous or maybe into flying and walking giants but it’s neither of them. Paleontologists have divided them into two main groups, saurischian ("lizard-hipped") and ornithischian ("bird-hipped") dinosaurs. Saurischians have both carnivorous and herbivorous variants while

ornithischians were only herbivorous.
