Would they meet?

No. Brachiosaurus and Grizzly Bear did not live at the same time. This meeting is pretend.

THE SCIENCE PICK

Brachiosaurus!

A STOMP · UNDERDOG

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

On forest, Brachiosaurus wins. Brachiosaurus is a lot heavier. Grizzly 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: Brachiosaurus 2 · Grizzly Bear 4 · ties 2.

Your card: Brachiosaurus 0 · Grizzly Bear 0.

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