Stegosaurus: Brains and Brawn
The Stegosaurus was a fascinating dinosaur known for its distinctive back plates and spiked tail. Despite its large body, it had a very small brain, often compared to the size of a walnut! This shows that not all animals need a large brain to survive. Its plates were likely for defense or showing off to other Stegosauruses. The spiked tail, called a 'thagomizer', was a powerful weapon against predators.
Why do you think a Stegosaurus needed big plates and a spiked tail, even with a small brain?

Read the size clue
Imagine a Stegosaurus! It was about 9.00 meters long, which is like three small cars parked bumper to bumper. It stood about 4.00 meters tall, as high as a giraffe or a two-story house. Its body was around 2.00 meters wide, wider than a large bed. This giant animal had a brain the size of a walnut, but plates on its back as big as dinner plates! Its huge size helped it stay safe from many predators.
