THE SCIENCE PICK

Spinosaurus!

A CLEAR PICK

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

On grassland, Spinosaurus wins. Spinosaurus is a lot heavier. Carnotaurus 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 2 · Spinosaurus 4 · ties 2.

Your card: Carnotaurus 0 · Spinosaurus 0.

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