A snout that may have sensed pressure in water, like a crocodile's face.

Boss of a Cretaceous river.

  • Spinosaurus is giant and not very fast.
  • Giant fish, and probably other animals that came to drink.

THE SCIENCE PICK

Spinosaurus!

A SQUEAKER

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

On river country, Spinosaurus wins. Spinosaurus likes river country more. Triceratops 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: Triceratops 3 · Spinosaurus 3 · ties 2.

Your card: Triceratops 0 · Spinosaurus 0.

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