Income per Second & Value
Reference income
On the community reference value, TRex is worth $25M/s — about $1.5B a minute, $90B an hour and $2.16T a day if the value holds. Above it in Prehistoric sits Tralaledon at $32M/s. The next one down is Bronto at $1.5M/s.
The listed value is the base one and the roll is a range, so no two copies have to agree with it. Nothing here is a trade price either: it is the reference value this site tracks for TRex.
Size and Mutation variance
This site prints no multiplier values for size or mutation, because none could be sourced. They stack on top of the base value rather than replacing it, which is why $25M/s is a floor-level figure rather than a maximum. The income calculator works from that figure, not from a guessed multiplier.
Rarity & Availability
Rarity label
TRex is Secret — one of the ten rarity labels this site uses, band 7 in its own ordering. 10 of the 15 pets carrying it have a confirmed value. Rarity is a label rather than a ladder: it says how the collection files the pet, not what it earns. The whole band is on the Secret pets page.
Acquisition/source
It is an egg-pool pet, listed in the Prehistoric collection — Endgame tier, and it opens at 17M Speed. The collection is described in full on the Prehistoric page.
How to Get TRex
Egg or event source
No source name is asserted here for TRex — turning a collection name into an egg name is exactly the kind of guess that makes a pet page wrong. What is known is the pool: Prehistoric, listed on the Prehistoric table. The site prints no odds, because none could be verified.
Requirements/progression gate
Prehistoric opens at 17M Speed, and its guardian is T-Rex. Because hatching is done in the world, the gate decides access: below it, this pet is out of reach. Its tier labelling is Endgame. The whole ladder is on the Prehistoric page.

Practical use
It is not the top of Prehistoric: Tralaledon is listed at $32M/s against its $25M/s, so within its own collection it is the option behind that one. At $90B an hour it is an endgame figure on this site's scale.
