THE SCIENCE PICK

Ankylosaurus!

A CLEAR PICK · UNDERDOG

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

On forest, Ankylosaurus wins. Ankylosaurus is a lot heavier. Allosaurus 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: Allosaurus 4 · Ankylosaurus 3 · ties 1.

Your card: Allosaurus 0 · Ankylosaurus 0.

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