THE SCIENCE PICK

Stegosaurus!

A CLEAR PICK · UNDERDOG

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

On grassland, Stegosaurus wins. Stegosaurus is a lot heavier. Carnotaurus 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: Stegosaurus 2 · Carnotaurus 3 · ties 3.

Your card: Stegosaurus 0 · Carnotaurus 0.

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