THE SCIENCE PICK

Parasaurolophus!

A STOMP · UNDERDOG

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

On river country, Parasaurolophus wins. Parasaurolophus 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 · Parasaurolophus 3 · ties 1.

Your card: Otter 0 · Parasaurolophus 0.

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