THE SCIENCE PICK

Carnotaurus!

A STOMP

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

On river country, Carnotaurus wins. Carnotaurus 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 3 · Carnotaurus 5.

Your card: Otter 0 · Carnotaurus 0.

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