THE SCIENCE PICK

Ankylosaurus!

A CLEAR PICK

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

On forest, Ankylosaurus wins. Ankylosaurus's tail-club sledge helps more. 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: Ankylosaurus 3 · Stegosaurus 1 · ties 4.

Your card: Ankylosaurus 0 · Stegosaurus 0.

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