THE SETUP

Spinosaurus vs Walrus

Spinosaurus

Walrus

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

Would they meet?

No. Spinosaurus and Walrus 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.

Spinosaurus is giant. 7,000 kg.

Walrus

Walrus is big. 900 kg.

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

Who would you pick for size?

TOOLKIT!

TOOLS

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

  • Weapon: Croc-snout plus canoe claws
  • Armor: Sail and dense bones

Meeting biome: the ice. Colored land is fossil range for dinosaurs and living range for zoo animals.

Spinosaurus

Wrong place · Lived in Africa long ago

Spinosaurus's home is the mid-cretaceous rivers of north africa, not the ice.

Walrus

This is home · Lives in North America / Asia / Europe

Walrus lives in places like the ice.

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

THE SCIENCE PICK

Spinosaurus!

A CLEAR PICK

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

On the ice, Spinosaurus wins. Spinosaurus is a lot heavier. Walrus 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 5 · Walrus 3.

Your card: Spinosaurus 0 · Walrus 0.

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