Most Interesting Facts About Dinosaurs

Dinosaurs are the most diverse group of reptiles and belong to the Dinosauria family. They had appeared in the Triassic period and had dominated the world 230 million years ago.

The exact origin and the reason for their distinction are unknown. However, it is believed that dinosaurs disappeared from the face of the earth due to climatic changes. Scientists believe that they died as they could not face the challenges and had lack of food. The fossil records also indicate that dinosaurs had features similar to modern-day animals and birds.

These giant creatures are usually divided into two main categories: avian dinosaurs and non-avian dinosaurs. The avian dinosaurs resemble birds like kiwis and others, while the non-avian dinosaurs possess features of reptiles.

It is believed that the dinosaurs had mover 20,000 different species, and the modern-day birds have more than 10,000 living species. This means the birds we see nowadays have properties and body parts similar to ancient dinosaurs.

While dinosaurs were ancestrally bipedal, various extinct groups consist of quadrupedal species. Some of them coped up with the environmental changes in a better way, and the others failed to survive in the harsh environments.

They had spines and other body parts that made them distinctive and prominent in a lot of ways. The dinosaurs were large-sized, but some of them were tiny enough to be seen with naked eyes. For their food, they primarily depended on other animals, birds, their eggs, and plants. They used to spend most of the time in deep forests and laid their eggs there.

The first dinosaur fossil was discovered in the early 19th century. Later on, the researchers dug deep and found a lot more fossils of them from the United States, Canada, Europe and other parts of the world. Today, they have become a part of history but have always fascinated the humans in the form of Hollywood films.
