Would they meet?

No. T. rex and Polar Bear did not live at the same time. This meeting is pretend.

THE SCIENCE PICK

T. rex!

A STOMP

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

On the ice, T. rex wins. T. rex is a lot heavier. Polar 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: T. rex 4 · Polar Bear 4.

Your card: T. rex 0 · Polar Bear 0.

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