Carnotaurus

Height to scale. A grown-up is 1.7 m.

Allosaurus1,700 kg

About the weight of a small car, hip-tall as a doorway, shorter than T. rex and quicker on the turn.

Carnotaurus1,400 kg

About as heavy as a small car, hip-tall as a doorway, with horns a bull would respect.

Allosaurus

Kilograms are honest. A small animal can still have a strong tool.

Who would you pick for size?

TOOLS

Teeth, claws, horns, venom, kick — what tools do they have?

THE SCIENCE PICK

Allosaurus!

A SQUEAKER

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

On grassland, Allosaurus wins. Allosaurus's hatchet bite plus hand claws helps more. 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: Allosaurus 4 · Carnotaurus 1 · ties 3.

Your card: Allosaurus 0 · Carnotaurus 0.

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