THE SETUP

Hippo vs T. rex

Hippo

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

Would they meet?

No. Hippo and T. rex 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.

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

Not their home · Lives in Africa

Hippo's home is the african rivers and lakes, not forest.

T. rex lives in places like forest.

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

Plants · Grazer by night.

Hippos graze grass at night.

T. rex

Meat · Giant bite-and-pull hunter.

Horned dinosaurs, duckbills, leftover carcasses — a giant meat-eater that did not skip free calories.

Hippo runs first. T. rex does not race. They wait in forest.

CHOMP!

THE TOOLS SHOW UP

T. rex is heavier. Hippo uses tusk-lined cave mouth. 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 forest, T. rex wins. T. rex likes forest more. Hippo 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: Hippo 2 · T. rex 2 · ties 4.

Your card: Hippo 0 · T. rex 0.

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