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

Would they meet?

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

Capybara
Splash Sit-In

Crest Trombone Blast

Capybara

Splash Sit-In

When trouble shows, they take the water.

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

Parasaurolophus!

A STOMP

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

On river country, Parasaurolophus wins. Parasaurolophus is a lot heavier. Capybara 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: Capybara 1 · Parasaurolophus 6 · ties 1.

Your card: Capybara 0 · Parasaurolophus 0.

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