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

Would they meet?

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

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

WILD CARD!

SPECIAL

What special move did they evolve?

Parasaurolophus
Crest Trombone Blast
Grizzly Bear
Salmon-Swipe Charge

Parasaurolophus

Crest Trombone Blast

Air through the hollow crest probably made a low honk.

Grizzly Bear

Salmon-Swipe Charge

They can outrun a horse for a short, extremely convincing burst.

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

THE SCIENCE PICK

Parasaurolophus!

A CLEAR PICK · UNDERDOG

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

On forest, Parasaurolophus wins. Parasaurolophus is a lot heavier. Grizzly Bear 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 1 · Grizzly Bear 5 · ties 2.

Your card: Parasaurolophus 0 · Grizzly Bear 0.

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