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

Would they meet?

No. T. rex lived in long ago. Allosaurus lived in long ago. Pretend meeting.

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!

Height to scale. A grown-up is 1.7 m.

T. rex8,200 kg

Hip-tall as a basketball hoop, heavier than an African elephant, longer than a school bus.

Allosaurus1,700 kg

About the weight of a small car, hip-tall as a doorway, shorter than T. rex and quicker on the turn.

T. rex

3.7 m · 8,200 kg

T. rex is giant. 8,200 kg.

Allosaurus

2.8 m · 1,700 kg

Allosaurus is huge. 1,700 kg.

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 · labeled field diagram

  • Weapon: Hatchet bite plus hand claws
  • Armor: Crested skull

Tool: hatchet bite plus hand claws. Bite: 2,000 psi.

A bite number is only one tool. Coils and kicks count too.

SPEED

Who gets there first?

Allosaurus

T. rex

20 km/h

T. rex can go 20 km/h. That is not very fast.

Allosaurus

32 km/h

Allosaurus can go 32 km/h. That is not very fast.

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

Who takes the speed card?

They meet in forest. Who is built for this place?

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

Meat · Hatchet-jaw hunter of the Jurassic.

T. rex

Meat · Giant bite-and-pull hunter.

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

Allosaurus

A plant eater is not 'safe.' Hippos and elephants still end arguments.

Whose hunting or defending helps more?

THEY MEET

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

WHOOSH!

THE TOOLS SHOW UP

T. rex is heavier. Allosaurus uses hatchet bite plus hand claws. 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 is a lot heavier. Allosaurus 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 · Allosaurus 1 · ties 1.

Your card: T. rex 0 · Allosaurus 0.

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