Kilograms are honest. A small animal can still have a strong tool.

Stegosaurus

Plate Parade Whip

The brain was famously small.

Ankylosaurus

Low-Profile Club

Crouch, armor up, wait for a leg to get greedy, then the tail does architecture.

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

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: Stegosaurus 1 · Ankylosaurus 3 · ties 4.

Your card: Stegosaurus 0 · Ankylosaurus 0.

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