Would they meet?

No. Ankylosaurus and Bison did not live at the same time. This meeting is pretend.

THE SCIENCE PICK

Ankylosaurus!

A STOMP

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

On grassland, Ankylosaurus wins. Ankylosaurus is a lot heavier. Bison 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: Ankylosaurus 3 · Bison 3 · ties 2.

Your card: Ankylosaurus 0 · Bison 0.

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