### What were dinosaurs?

What is a small introduction about dinosaurs?

1. Dinosaurs were a group of reptiles that dominated the planet millions of years ago. They were incredibly diverse, ranging from small, bird-like creatures to massive, carnivorous predators.

2. These creatures walked on two legs, had sharp teeth, and some even had feathers. They were well-adapted to their environments and played a crucial role in the ecosystems of the time.

3. Dinosaurs were not the only reptiles that lived during the Mesozoic Era. Other creatures, such as pterosaurs and marine reptiles, also roamed the Earth alongside dinosaurs.

### When did dinosaurs exist?

1. Dinosaurs lived during the Mesozoic Era, which is divided into three periods: the Triassic, Jurassic, and Cretaceous periods.

2. They first appeared during the Triassic period around 230 million years ago and went extinct at the end of the Cretaceous period around 65 million years ago.

3. Dinosaurs ruled the Earth for over 150 million years, making them one of the most successful groups of animals in Earth's history.

### What happened to the dinosaurs?

1. The extinction of dinosaurs is still a topic of debate among scientists. One of the most widely accepted theories is that a massive asteroid impact caused a chain reaction of events that led to their extinction.

2. The impact caused widespread fires, tsunamis, and a darkened sky due to debris in the atmosphere, which disrupted the food chain and ultimately led to the demise of many species, including the dinosaurs.

3. While some dinosaurs went extinct, others evolved into birds, which are considered the only surviving descendants of these magnificent creatures.

In conclusion, dinosaurs were an incredible group of reptiles that dominated the Earth for millions of years. Their fascinating anatomy, behavior, and extinction continue to be a subject of study and fascination for researchers and the general public alike.
