Sloth vs Parasaurolophus
Pretend they meet in forest. Dinosaurs lived long ago. Look at the facts. Then you pick.
Would they meet?
No. Sloth and Parasaurolophus 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.

FOOD
How do they get lunch?
Sloth
Plants · Leaf eater in slow motion.
Leaves.
Parasaurolophus
Plants · Does not hunt.
Plants ground by a dental battery — a whole chalkboard of replacement teeth.
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.
Sloth
Lives alone
Peaceful to a fault. Grit: 5/10.
Parasaurolophus
Lives in a herd
Nervy salad. Grit: 5/10.
Pack and pride animals lose their backup in a 1-v-1.
Who is better for a solo meeting?
BRAINS

Sloth
3/10
Not a hunter's kit.
Parasaurolophus
4/10
The crest was a horn.
In the wild, brains often mean leave before it starts.
Who would you score for noticing?

Sloth
Bradypus variegatus
Anteaters and armadillos — the xenarthran club of unhurried specialists.
Parasaurolophus
Parasaurolophus walkeri
Other hadrosaurs: Edmontosaurus, Corythosaurus, and the duckbill crowd.
Cousins are clues, not a score.
Not a fight point. Who has the wilder family story?
SPECIAL
What special move did they evolve?
Sloth
Hang In There
Predators often cannot peel a sloth off a branch.
Parasaurolophus
Crest Trombone Blast
Air through the hollow crest probably made a low honk.

Whose special move would change the meeting?

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