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

Would they meet?

No. Spinosaurus and Okapi 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.

Spinosaurus

River-Ambush Paddle

Spinosaurus was built to hunt in rivers.

THE SCIENCE PICK

Spinosaurus!

A STOMP

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

On forest, Spinosaurus wins. Spinosaurus is a lot heavier. Okapi 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: Spinosaurus 5 · Okapi 3.

Your card: Spinosaurus 0 · Okapi 0.

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