THE SETUP

Spinosaurus vs Gazelle

Spinosaurus
Gazelle
Gazelle

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

Would they meet?

No. Spinosaurus and Gazelle 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

Eudorcas thomsonii · A spring with horns and a stotting hobby.

Grazer.

Side-set eyes for a wraparound view.

Nervous athlete.

  • Gazelle is small and very fast.
  • Short grass.
  • Open plains where a lookout and a sprint are the whole security system.

Family: Antelopes and impalas.

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.

Gazelle25 kg

About as heavy as a second-grader, twice as bouncy.

Spinosaurus

2.8 m · 7,000 kg

Spinosaurus is giant. 7,000 kg.

Gazelle

0.70 m · 25 kg

Gazelle is small. 25 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.

Gazelle

80 km/h

Gazelle can go 80 km/h. That is very fast.

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

Meeting biome: grassland. 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 grassland.

Gazelle

This is home · Lives in Africa

Gazelle lives in places like grassland.

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

Spinosaurus

Meat · River specialist.

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

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 grassland, Spinosaurus wins. Spinosaurus is a lot heavier. Gazelle 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 · Gazelle 3.

Your card: Spinosaurus 0 · Gazelle 0.

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