Pretend they meet in grassland. Dinosaurs lived long ago. Look at the facts. Then you pick.

Would they meet?

No. Stegosaurus and Ostrich did not live at the same time. This meeting is pretend.

This is pretend and based on facts. Real animals usually hide or leave.

Read the facts. Make your card. The page waits to pick.

Kilograms are honest. A small animal can still have a strong tool.

Who would you pick for size?

TOOLKIT!

TOOLS

Teeth, claws, horns, venom, kick — what tools do they have?

  • Weapon: Thagomizer tail spikes

WHOOSH!

THE SCIENCE PICK

Stegosaurus!

A STOMP

You skipped a final pick. The facts still stamp a champ.

On grassland, Stegosaurus wins. Stegosaurus is a lot heavier. Ostrich would still win some meetings at home.

In the wild, most animals skip a fight. We still judge who the bodies and the place would favor.

Science card: Stegosaurus 3 · Ostrich 2 · ties 3.

Your card: Stegosaurus 0 · Ostrich 0.

The last page follows the whole animal — body plus home — not one bar chart.
