Parasaurolophus

Pretend a carnotaurus and a parasaurolophus meet in river country. Look at the facts. Then you pick.

Would they meet?

No. Wild carnotauruss and parasaurolophuss would not meet. We still look at the facts.

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

Read the facts. Make your card. The page waits to pick.

Carnotaurus

Patagonia Sprint Horns

The tail and legs look built for speed.

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

Carnotaurus!

A SQUEAKER

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

On river country, Carnotaurus wins. Carnotaurus's horned skull plus a meat-slicer jaw 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: Carnotaurus 4 · Parasaurolophus 2 · ties 2.

Your card: Carnotaurus 0 · Parasaurolophus 0.

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