THE SCIENCE PICK

Allosaurus!

A STOMP

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

On grassland, Allosaurus wins. Allosaurus is a lot heavier. Kangaroo 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: Allosaurus 3 · Kangaroo 3 · ties 2.

Your card: Allosaurus 0 · Kangaroo 0.

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