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

Would they meet?

No. Anaconda and Spinosaurus 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.

Eunectes murinus · A river rope that forgot it is allowed to be this heavy.

Size
Anaconda is big.

Wait in the water, coil, squeeze.

Heat pits plus a swimmer's patience.

Heavy and unhurried.

  • Anaconda is big and slow.
  • Capybara, fish, birds, caimans — if it comes to the water's edge, it is on the maybe list.
  • Slow rivers and swamps.

Family: Boas.

Corner B

Spinosaurus

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

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.

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: Coil squeeze
  • Armor: Water-slick muscle

Anaconda

8 km/h

Anaconda can go 8 km/h. That is slow.

Spinosaurus

Spinosaurus can go 18 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

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

On river country, Spinosaurus wins. Spinosaurus is a lot heavier. Anaconda 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: Anaconda 1 · Spinosaurus 2 · ties 5.

Your card: Anaconda 0 · Spinosaurus 0.

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