Stegosaurus
Thagomizer tail spikes
Tool: thagomizer tail spikes. Bite: 200 psi.
Spinosaurus
Croc-snout plus canoe claws

A fast animal can miss. A slow one only has to connect.
Who takes the speed card?
HOME
They meet in grassland. Who is built for this place?
Meeting biome: grassland. Colored land is fossil range for dinosaurs and living range for zoo animals.
Stegosaurus

Spinosaurus's home is the mid-cretaceous rivers of north africa, not grassland.

Who gets the home point?
FOOD
How do they get lunch?
Stegosaurus
Plants · Browser.
Low plants.
Spinosaurus
Meat · River specialist.
Giant fish, and probably other animals that came to drink.
A plant eater is not 'safe.' Hippos and elephants still end arguments.
Whose hunting or defending helps more?
MOOD
Alone vs team. This rumble is one vs one.
Stegosaurus
Lives in a herd
Slow salad tank. Grit: 7/10.
Spinosaurus
Lives alone
Boss of a Cretaceous river. Grit: 7/10.
Pack and pride animals lose their backup in a 1-v-1.
Who is better for a solo meeting?
BRAINS
Who notices first and thinks next?
Stegosaurus
2/10
A tiny brain, a low head, and a tail that did not wait for a committee.
Spinosaurus
4/10
A snout that may have sensed pressure in water, like a crocodile's face.
In the wild, brains often mean leave before it starts.
Who would you score for noticing?
FAMILY
Who are they related to?
Stegosaurus
Stegosaurus stenops
Other plated dinosaurs like Kentrosaurus.
Spinosaurus
Spinosaurus aegyptiacus
Other spinosaurids like Baryonyx and Suchomimus.
Cousins are clues, not a score.
Not a fight point. Who has the wilder family story?
SPECIAL
What special move did they evolve?
Stegosaurus
Plate Parade Whip
The brain was famously small.
Spinosaurus
River-Ambush Paddle
Spinosaurus was built to hunt in rivers.
A secret move here is a real wild tool, not a video-game combo.

Keep going for the pretend meeting, then the science pick.
THEY MEET
Spinosaurus runs first. Stegosaurus does not race. They wait in grassland.
Pretend · fact-based · not a gore-fest
THE TOOLS SHOW UP
Spinosaurus is heavier. Stegosaurus uses thagomizer tail spikes. Nobody is keeping a gore score.

Stegosaurus tries the Plate Parade Whip. Spinosaurus tries the River-Ambush Paddle. Keep your card. The last page is next.

Spinosaurus!
A SQUEAKER
You skipped a final pick. The facts still stamp a champ.
On grassland, Spinosaurus wins. Spinosaurus is a lot heavier. Stegosaurus 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: Stegosaurus 2 · Spinosaurus 6.
Your card: Stegosaurus 0 · Spinosaurus 0.
The last page follows the whole animal — body plus home — not one bar chart.
