Pretend they meet in river country. Dinosaurs lived long ago. Look at the facts. Then you pick.

Would they meet?

No. Parasaurolophus and Crocodile did not live at the same time. This meeting is pretend.

This is pretend and based on facts. Real animals usually hide or leave.

Parasaurolophus

Crest Trombone Blast

Air through the hollow crest probably made a low honk.

Death-Roll Remix

If it grabs you, it spins.

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

THE SCIENCE PICK

Crocodile!

A SQUEAKER

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

On river country, Crocodile wins. Crocodile's the planet's hardest chomp 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 · Crocodile 5 · ties 1.

Your card: Parasaurolophus 0 · Crocodile 0.

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