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

Would they meet?

No. Spinosaurus lived in long ago. Parasaurolophus lived in long ago. Pretend meeting.

This is pretend and based on facts. Real animals usually hide or leave.

Read the facts. Make your card. The page waits to pick.

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.

Longer than T. rex, maybe as long as a city bus, with a sail that could top a doorway.

Parasaurolophus2,500 kg

About as heavy as a rhinoceros, with a head-crest as long as a baseball bat.

Spinosaurus

Parasaurolophus is huge. 2,500 kg.

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

TOOLKIT!

TOOLS

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

  • Weapon: Croc-snout plus canoe claws
  • Armor: Sail and dense bones
  • Senses: A snout that may have sensed pressure in water, like a crocodile's face.

Spinosaurus can go 18 km/h. That is not very fast.

Parasaurolophus can go 40 km/h. That is fast.

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

SPECIAL

What special move did they evolve?

Spinosaurus
River-Ambush Paddle
Parasaurolophus
Crest Trombone Blast

Spinosaurus

River-Ambush Paddle

Spinosaurus was built to hunt in rivers.

Parasaurolophus

Crest Trombone Blast

Air through the hollow crest probably made a low honk.

A secret move here is a real wild tool, not a video-game combo.

Whose special move would change the meeting?

Parasaurolophus runs first. Spinosaurus does not race. They wait in river country.

Spinosaurus is heavier. Parasaurolophus uses herd, kick, and a honk. Nobody is keeping a gore score.

THE SCIENCE PICK

Spinosaurus!

A STOMP

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

On river country, Spinosaurus wins. Spinosaurus is a lot heavier. Parasaurolophus 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 6 · Parasaurolophus 1 · ties 1.

Your card: Spinosaurus 0 · Parasaurolophus 0.

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