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

Would they meet?

No. Tortoise 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.

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!

THE SCIENCE PICK

T. rex!

A STOMP

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

On the island, T. rex wins. T. rex is a lot heavier. Tortoise 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: Tortoise 1 · T. rex 7.

Your card: Tortoise 0 · T. rex 0.

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