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

Would they meet?

No. Spinosaurus and Koala 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.

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

Koala

Phascolarctos cinereus · A sleepy specialist with surprising claws.

Size
Koala is small.

Eucalyptus specialist.

A nose for the right leaves.

Low-energy by design.

  • Koala is small and slow.
  • Almost only eucalyptus.
  • They pick a tree, claim it, and treat the canopy like a studio apartment.

Family: Wombats.

Height to scale. A grown-up is 1.7 m.

Spinosaurus7,000 kg

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

Koala10 kg

About as heavy as a bowling ball that insists it is a teddy.

Spinosaurus

2.8 m · 7,000 kg

Spinosaurus is giant. 7,000 kg.

Koala

0.60 m · 10 kg

Koala is small. 10 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
  • Senses: A snout that may have sensed pressure in water, like a crocodile's face.

Spinosaurus

18 km/h

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

Koala

10 km/h

Koala can go 10 km/h. That is slow.

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

HOME MAP!

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

Spinosaurus

Not their home · Lived in Africa long ago

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

Koala

This is home · Lives in Australia

Koala lives in places like forest.

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

Who gets the home point?

Spinosaurus

Meat · River specialist.

Giant fish, and probably other animals that came to drink.

Koala

Plants · Eucalyptus specialist.

Almost only eucalyptus.

A plant eater is not 'safe.' Hippos and elephants still end arguments.

Whose hunting or defending helps more?

THE SCIENCE PICK

Spinosaurus!

A STOMP

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

On forest, Spinosaurus wins. Spinosaurus is a lot heavier. Koala 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 · Koala 1 · ties 1.

Your card: Spinosaurus 0 · Koala 0.

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