THE SETUP

Spinosaurus vs Sea Lion

Spinosaurus
Spinosaurus
Sea Lion
Sea Lion

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

Would they meet?

No. Spinosaurus and Sea Lion 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

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

Sea Lion is big.

Fish chaser in the surf.

Whiskers read fish in murk.

Playful and noisy.

  • Sea Lion is big and not very fast.
  • Fish, squid, and the occasional unfortunate leftover from the ocean buffet.
  • Rocky coasts and piers, where barking is a civic duty.

Family: Fur seals and walruses.

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

Sea Lion

Sea Lion can go 30 km/h. That is not very fast.

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

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

Spinosaurus

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

Sea Lion lives in places like the coast.

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

THE SCIENCE PICK

Spinosaurus!

A STOMP

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

On the coast, Spinosaurus wins. Spinosaurus is a lot heavier. Sea Lion 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 · Sea Lion 3.

Your card: Spinosaurus 0 · Sea Lion 0.

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