Pretend they meet in forest. Dinosaurs lived long ago. Look at the facts. Then you pick.

Would they meet?

No. Spinosaurus and Cassowary did not live at the same time. This meeting is pretend.

This is pretend and based on facts. Real animals usually hide or leave.

Read the facts. Make your card. The page waits to pick.

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.
  • Cretaceous North Africa, about 95 million years ago — rivers and mangrove-ish coasts, not the Serengeti.

Family: Other spinosaurids like Baryonyx and Suchomimus.

Fruit eater with dinosaur feet.

Casque and low rumble carry through forest.

Shy until cornered.

  • Cassowary is medium and fast.

Spinosaurus

Not their home · Lived in Africa long ago

Cassowary lives in places like forest.

No. Spinosaurus and Cassowary did not live at the same time. This meeting is pretend.

Meat · River specialist.

Giant fish, and probably other animals that came to drink.

THE SCIENCE PICK

Spinosaurus!

A STOMP

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

On forest, Spinosaurus wins. Spinosaurus is a lot heavier. Cassowary 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: Spinosaurus 3 · Cassowary 2 · ties 3.

Your card: Spinosaurus 0 · Cassowary 0.

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