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

Would they meet?

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

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

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

What special move did they evolve?

Koala
Eucalyptus Power Nap
Parasaurolophus
Crest Trombone Blast

Koala

Eucalyptus Power Nap

Koalas sleep up to 18 hours.

Parasaurolophus

Air through the hollow crest probably made a low honk.

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

Parasaurolophus runs first. Koala does not race. They wait in forest.

KICK!

THE TOOLS SHOW UP

Parasaurolophus is heavier. Koala uses tree-hook claws. Nobody is keeping a gore score.

THE SCIENCE PICK

Parasaurolophus!

A STOMP

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

On forest, Parasaurolophus wins. Parasaurolophus is a lot heavier. Koala 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: Koala 0 · Parasaurolophus 6 · ties 2.

Your card: Koala 0 · Parasaurolophus 0.

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