TOOLKIT!

TOOLS

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

Open wide, strike down, pull back.

A secret move here is a real wild tool, not a video-game combo.

THE SCIENCE PICK

Allosaurus!

A CLEAR PICK

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

On forest, Allosaurus wins. Allosaurus's hatchet bite plus hand claws helps more. Parasaurolophus 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: Parasaurolophus 2 · Allosaurus 3 · ties 3.

Your card: Parasaurolophus 0 · Allosaurus 0.

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