THE SCIENCE PICK

Brachiosaurus!

A STOMP

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

On forest, Brachiosaurus wins. Brachiosaurus is a lot heavier. Parasaurolophus 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: Brachiosaurus 4 · Parasaurolophus 2 · ties 2.

Your card: Brachiosaurus 0 · Parasaurolophus 0.

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