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

Would they meet?

No. Cassowary and Spinosaurus 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.

Corner A

Lives alone
Size
Cassowary is medium.

Fruit eater with dinosaur feet.

Casque and low rumble carry through forest.

Shy until cornered.

  • Cassowary is medium and fast.
  • Mostly fruit.
  • Dense rainforest where a tall dark bird can appear like a jump scare.

Family: Emus and ostriches — the ratite squad of giant flightless birds.

Corner B

Spinosaurus

Spinosaurus aegyptiacus · A sail-backed river hunter longer than a bus.

Size
Spinosaurus is giant.

River specialist.

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.

THE SCIENCE PICK

Spinosaurus!

A STOMP

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

On river country, Spinosaurus wins. Spinosaurus likes river country more. 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: Cassowary 1 · Spinosaurus 4 · ties 3.

Your card: Cassowary 0 · Spinosaurus 0.

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