THE SETUP

Spinosaurus vs Leopard

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

Would they meet?

No. Spinosaurus and Leopard 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.

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.

Corner B

Night specialist.

Secretive and bold.

  • Leopard is medium and fast.
  • Antelope, monkeys, birds — leopards are not picky, just sneaky.
  • They live just about everywhere a tree or a rocky hideout exists.

Family: Lion, tiger, jaguar — the roaring cousins with different fashion.

About as heavy as a fifth-grader, with much better climbing grades.

Spinosaurus

Spinosaurus is giant. 7,000 kg.

Leopard

0.70 m · 60 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

Spinosaurus lives in places like river country.

Leopard's home is the african and asian woodland, not river country.

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. Leopard 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 · Leopard 3.

Your card: Spinosaurus 0 · Leopard 0.

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