Would they meet?

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

THE SCIENCE PICK

Stegosaurus!

A SQUEAKER · UNDERDOG

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

On the ice, Stegosaurus wins. Stegosaurus is a lot heavier. Walrus 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 · Walrus 4 · ties 1.

Your card: Stegosaurus 0 · Walrus 0.

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