Would they meet?

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

THE SCIENCE PICK

Parasaurolophus!

A STOMP · UNDERDOG

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

On forest, Parasaurolophus wins. Parasaurolophus is a lot heavier. Jaguar 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 · Jaguar 6 · ties 1.

Your card: Parasaurolophus 0 · Jaguar 0.

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