Isn't Dinosaurs Really Completely Extinct

It is always exciting to hear stories about the dinosaur age. But did you know that there was a group of creatures even older than the dinosaurs, called archosaurs? This group of creatures existed on Earth millions of years ago and some of its creatures are still alive today.

Archosaurs: Ancient "Ruler Reptiles"

Archosaur means "ruler reptile." It was an ancient reptile group that emerged on Earth about 250 million years ago. At that time, archosaurs were quite dominant on Earth. Dinosaurs, birds and crocodiles are all considered to be descendants of this ancient group. Archosaurs evolved from amphibians, which lived both in water and on land.

The relationship between dinosaurs and archosaurs

Dinosaurs evolved from archosaurs. It is believed that archosaurs were of different sizes and types, and from them different types of dinosaurs were developed. These dinosaurs ruled the earth for millions of years and were in many different sizes and shapes.

Birds and crocodiles evolved from archosaurs

Some members of the archosaur order later evolved into birds. The development of feathers and the ability to fly made birds distinct from other organisms. Their ability to fly allowed them to reach new areas and live in a variety of habitats.

Crocodiles are also descendants of archosaurs. It is interesting that crocodiles exist today in almost the same form as they did millions of years ago. There have been very few changes in their appearance, which makes one feel that these creatures have adapted themselves well in nature.

Why is the study of archeosaurs important?

By studying archosaur fossils, scientists are able to learn about Earth's history and the evolution of life. The remains of these organisms tell us what kinds of organisms lived on Earth and how they adapted to changing environments. Studying these organisms also helps us understand present-day organisms, especially which ancient organisms are related to today.

Contributions of archosaurs

Not only were archosaurs a family of dinosaurs, but many of their descendants are still among us today. Studying these ancient reptiles is a way to get a glimpse into Earth's past, which helps us understand how life evolved and how different species came into being.
