Would they meet?

No. T. rex and Komodo Dragon 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 grassland, T. rex wins. T. rex is a lot heavier. Komodo Dragon 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 5 · Komodo Dragon 0 · ties 3.

Your card: T. rex 0 · Komodo Dragon 0.

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