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

Would they meet?

No. T. rex and Cheetah 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.

Size
T. rex is giant.

Giant bite-and-pull hunter.

A huge smelling system and eyes that faced more forward than most dinosaurs.

Top of a vanished food web.

  • T. rex is giant and not very fast.
  • Horned dinosaurs, duckbills, leftover carcasses — a giant meat-eater that did not skip free calories.
  • Fossils come from places like Hell Creek: forests, rivers, and floodplains about 66 million years ago.

Family: Birds!

Cheetah is medium.

Sprint specialist.

Huge eyes, huge field of view.

A sprinter, not a wrestler.

  • Cheetah is medium and very fast.
  • They prefer gazelles and other speedy snacks they can outrun.
  • Open plains are a racetrack.

Family: Other cats, but cheetahs are the odd cousins who joined track team.

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: Banana-sized bone shears
  • Armor: Thick skull and a neck like a crane
  • Senses: A huge smelling system and eyes that faced more forward than most dinosaurs.

T. rex can go 20 km/h. That is not very fast.

Cheetah can go 110 km/h. That is very fast.

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

THE SCIENCE PICK

T. rex!

A STOMP

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

On grassland, T. rex wins. T. rex is a lot heavier. Cheetah 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: T. rex 4 · Cheetah 3 · ties 1.

Your card: T. rex 0 · Cheetah 0.

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