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

Would they meet?

No. Spinosaurus and Lion 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.

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.

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?

  • Weapon: Croc-snout plus canoe claws

THE SCIENCE PICK

Spinosaurus!

A STOMP · UNDERDOG

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

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

Your card: Spinosaurus 0 · Lion 0.

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