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

Would they meet?

No. T. rex and Penguin 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.

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!

Torpedo fisher.

Underwater vision is the talent.

Tough about cold.

  • Penguin is medium and slow.
  • Fish, krill, and squid, caught in icy dives.
  • They huddle in storms so tight that the inside of the huddle is toasty.

Family: Other flightless seabirds.

T. rex is giant. 8,200 kg.

Penguin

1.20 m · 40 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: 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 · labeled field diagram

SPEED

Who gets there first?

T. rex

20 km/h

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

Penguin

8 km/h

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

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

Who takes the speed card?

HOME MAP!

HOME

They meet in grassland. Who is built for this place?

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

This is home · Lived in North America long ago

T. rex lives in places like grassland.

Wrong place · Lives in Antarctica

Penguin's home is the antarctic ice, not grassland.

No. T. rex and Penguin did not live at the same time. This meeting is pretend.

T. rex runs first. Penguin does not race. They wait in grassland.

T. rex is heavier. Penguin uses flipper slap + beak poke. Nobody is keeping a gore score.

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 likes grassland more. Penguin 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 7 · Penguin 1.

Your card: T. rex 0 · Penguin 0.

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