THE SCIENCE PICK

Triceratops!

A CLEAR PICK

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

On grassland, Triceratops wins. Triceratops is a lot heavier. Stegosaurus 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: Triceratops 6 · Stegosaurus 0 · ties 2.

Your card: Triceratops 0 · Stegosaurus 0.

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