Would they meet?

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

THE SCIENCE PICK

Carnotaurus!

A STOMP

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

On grassland, Carnotaurus wins. Carnotaurus likes grassland more. 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: Carnotaurus 7 · Koala 0 · ties 1.

Your card: Carnotaurus 0 · Koala 0.

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