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

Would they meet?

No. Polar Bear and Spinosaurus 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.

THE SCIENCE PICK

Spinosaurus!

A CLEAR PICK · UNDERDOG

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

On the ice, Spinosaurus wins. Spinosaurus is a lot heavier. Polar Bear 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: Polar Bear 4 · Spinosaurus 2 · ties 2.

Your card: Polar Bear 0 · Spinosaurus 0.

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