T. rex
Banana-sized bone shears

Brachiosaurus
Column legs plus a neck crane

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

T. rex
Meat · Giant bite-and-pull hunter.
Horned dinosaurs, duckbills, leftover carcasses — a giant meat-eater that did not skip free calories.
Brachiosaurus

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

Brachiosaurus!
A SQUEAKER · UNDERDOG
You skipped a final pick. The facts still stamp a champ.
On forest, Brachiosaurus wins. Brachiosaurus is a lot heavier. T. rex 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 5 · Brachiosaurus 1 · ties 2.
Your card: T. rex 0 · Brachiosaurus 0.
The last page follows the whole animal — body plus home — not one bar chart.
