Pretend a t. rex and a ankylosaurus meet in forest. Look at the facts. Then you pick.

Would they meet?

Yes. They could meet in the real wild. This page is still a what-if.

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!

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.

Ankylosaurus

Ankylosaurus can go 10 km/h. That is slow.

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

THE SCIENCE PICK

T. rex!

A CLEAR PICK

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

On forest, T. rex wins. T. rex's banana-sized bone shears helps more. Ankylosaurus 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 5 · Ankylosaurus 1 · ties 2.

Your card: T. rex 0 · Ankylosaurus 0.

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