What special move did they evolve?

Stegosaurus
Plate Parade Whip
Parasaurolophus
Crest Trombone Blast

Stegosaurus

Plate Parade Whip

The brain was famously small.

Parasaurolophus

Crest Trombone Blast

Air through the hollow crest probably made a low honk.

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

THE SCIENCE PICK

Stegosaurus!

A CLEAR PICK

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

On forest, Stegosaurus wins. Stegosaurus's thagomizer tail spikes 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: Stegosaurus 4 · Parasaurolophus 2 · ties 2.

Your card: Stegosaurus 0 · Parasaurolophus 0.

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