Dinosaurs

For 165 million years they ruled the Earth. Then they were gone — almost. (Birds are still here.)

When did they live? ⏳

If all of Earth's history were squashed into one school day, dinosaurs would have walked around for about 30 minutes. Humans would arrive in the very last 2 seconds.

252–201
million years ago

Triassic

First dinosaurs appear — small, fast, dog-sized. Most of Earth was one giant continent called Pangaea.

201–145
million years ago

Jurassic

Giant long-necks like Brachiosaurus. Stegosaurus with the spiky back. The "classic" dinosaurs.

145–66
million years ago

Cretaceous

T. Rex, Triceratops, Velociraptor. Flowers appear for the first time. Then — boom.

66 million
years ago

The big asteroid 💥

A space rock the size of a city smashed into Mexico. Three quarters of all life on Earth died, including all the big dinosaurs.

Six famous ones 🦖

🦖

Tyrannosaurus rex

Cretaceous · meat-eater

12 metres long, teeth 20 cm. Tiny arms but a bite that could crush a car.

🦕

Brachiosaurus

Jurassic · plant-eater

Tall as a 4-storey building. Spent the day eating leaves from the tops of trees.

🛡️

Triceratops

Cretaceous · plant-eater

Three horns and a giant frill on its head. Probably fought off T. rex with the horns.

🪶

Velociraptor

Cretaceous · meat-eater

Real ones were the size of a turkey, with feathers — not the giant scaly ones in the films.

🌿

Stegosaurus

Jurassic · plant-eater

Plates on its back to soak up sun. Brain the size of a walnut, body the size of a bus.

🐦

Birds

Today · still here

Yes — pigeons, sparrows, chickens. They're the descendants of small feathered dinosaurs that survived the asteroid.

The Big Idea

The dinosaurs aren't all gone 🦜

Every time you see a sparrow on the pavement, a chicken at lunch, or a pigeon at the park — you're looking at a tiny dinosaur. Birds are the only kind of dinosaur that lived through the asteroid.

So humans and dinosaurs have met. Just feathered, smaller versions.
