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

Would they meet?

No. Allosaurus and Rattlesnake 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.

Kilograms are honest. A small animal can still have a strong tool.

Who would you pick for size?

TOOLKIT!

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

Allosaurus

This is home · Lived in North America long ago

Allosaurus lives in places like grassland.

Rattlesnake

Can handle it · Lives in North America

Rattlesnake's home is the north american deserts, not grassland.

No. Allosaurus and Rattlesnake did not live at the same time. This meeting is pretend.

THE SCIENCE PICK

Allosaurus!

A STOMP

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

On grassland, Allosaurus wins. Allosaurus likes grassland more. Rattlesnake 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: Allosaurus 6 · Rattlesnake 0 · ties 2.

Your card: Allosaurus 0 · Rattlesnake 0.

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