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

Would they meet?

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

Parasaurolophus's home is the late cretaceous forests of western north america, not the ice.

SPECIAL

What special move did they evolve?

Walrus
Tusk-Hook Haul
Parasaurolophus
Crest Trombone Blast

Walrus

Tusk-Hook Haul

They can hook ice, bellow, and make a beach of other pinnipeds scoot over.

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.

Whose special move would change the meeting?

THE SCIENCE PICK

Walrus!

A CLEAR PICK

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

On the ice, Walrus wins. Walrus likes the ice 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: Walrus 5 · Parasaurolophus 3.

Your card: Walrus 0 · Parasaurolophus 0.

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