THE SETUP

Spinosaurus vs Crocodile

Spinosaurus

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

Would they meet?

No. Spinosaurus and Crocodile 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

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

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

Crocodylus niloticus · A living fossil with a trapdoor mouth.

Crocodile is big.

Wait like a log.

Pressure sensors in the skin feel a ripple.

Explosive from zero.

  • Crocodile is big and not very fast.
  • Fish, mammals, birds — if it comes to the water's edge, it is on the menu.
  • They wait like logs.

Family: Alligators, caimans, and dinosaurs' old roommates, the archosaurs.

Spinosaurus is giant. 7,000 kg.

Crocodile

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

Crocodile can go 32 km/h. That is not very fast.

A fast animal can miss. A slow one only has to connect.

THE SCIENCE PICK

Spinosaurus!

A STOMP · UNDERDOG

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

On river country, Spinosaurus wins. Spinosaurus is a lot heavier. Crocodile 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 1 · Crocodile 4 · ties 3.

Your card: Spinosaurus 0 · Crocodile 0.

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