TOOLS

Teeth, claws, horns, venom, kick — what tools do they have?

THE SCIENCE PICK

Allosaurus!

A SQUEAKER

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

On grassland, Allosaurus wins. Allosaurus's hatchet bite plus hand claws helps more. 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: Carnotaurus 1 · Allosaurus 4 · ties 3.

Your card: Carnotaurus 0 · Allosaurus 0.

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