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

Would they meet?

No. Otter and Ankylosaurus 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 river country, Ankylosaurus wins. Ankylosaurus is a lot heavier. Otter 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: Otter 4 · Ankylosaurus 4.

Your card: Otter 0 · Ankylosaurus 0.

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