Age of ancient reptiles

 The “Age of Ancient Reptiles” usually refers to the Mesozoic Era, when reptiles—especially dinosaurs—dominated life on Earth. 🦖

🦎 Timeline of the Age of Reptiles

1. 

Triassic Period (252–201 million years ago)

• Begins after the massive Permian–Triassic Extinction Event.
• Early reptiles diversify.
• First dinosaurs and mammals appear.
• The supercontinent Pangaea still exists.

Examples of reptiles:

• Early dinosaurs
• Marine reptiles like ichthyosaurs

2. 

Jurassic Period (201–145 million years ago)

• Dinosaurs become the dominant land animals.
• Large sauropods appear.
• First birds evolve from dinosaurs, such as Archaeopteryx.

Famous dinosaurs:

• Stegosaurus
• Brachiosaurus

3. 

Cretaceous Period (145–66 million years ago)

• Flowering plants evolve.
• Many famous dinosaurs live during this time.

Examples:

• Tyrannosaurus rex
• Triceratops

The era ends with the Cretaceous–Paleogene Extinction Event about 66 million years ago.

Jurassic	201–145 MYA	Dinosaurs dominate land
Cretaceous	145–66 MYA	Peak dinosaur diversity

✔️ Even today, birds are actually living dinosaurs, meaning the age of reptiles never completely ended. 🐦
