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

Would they meet?

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

THE SCIENCE PICK

Stegosaurus!

A STOMP · UNDERDOG

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

On grassland, Stegosaurus wins. Stegosaurus is a lot heavier. Kangaroo 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 2 · Kangaroo 3 · ties 3.

Your card: Stegosaurus 0 · Kangaroo 0.

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