Would they meet?

No. Stegosaurus and Cassowary 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 forest, Stegosaurus wins. Stegosaurus is a lot heavier. Cassowary 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 · Cassowary 4 · ties 2.

Your card: Stegosaurus 0 · Cassowary 0.

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