T. rex vs Sea Lion

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

Would they meet?

No. T. rex and Sea Lion 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!

Playful and noisy.

  • Sea Lion is big and not very fast.
  • Fish, squid, and the occasional unfortunate leftover from the ocean buffet.
  • Rocky coasts and piers, where barking is a civic duty.

Family: Fur seals and walruses.

Who would you pick for size?

TOOLKIT!

Teeth, claws, horns, venom, kick — what tools do they have?

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. Sea Lion 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 6 · Sea Lion 2.

Your card: T. rex 0 · Sea Lion 0.

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