All playable dinosaurs within the game have a Growth Rate Multiplier (GRM). This determines how fast the dinosaur takes to grow, along with affecting many other statistics in-game. The time it takes to grow from a baby to elder is determined by the growth rate.
The lower the growth rate, the faster the dinosaur grows, vice-versa being the higher the growth rate, the slower the dinosaur grows.
It is used to "balance" dinosaur stats; Generally stronger, better dinosaurs with higher base stats have a higher growth rate, while weaker dinosaurs with low base stats have a lower growth rate.
- The animal with the highest growth rate, which grows the slowest, is the Barosaurus, with a 3.0 GRM.
- The animals with the lowest growth rate, which grows the fastest, are Coelacanth and Megalodon, with a 0.1 GRM.
Relation Between GRM and DNA
A certain amount of DNA is awarded to players for every day alive, along with life stage evolution. As of Update Ver[4.1.2], the amount of DNA awarded per day depends on the growth rate of the dinosaur being played as and the value of the day. The amount of days passed is multiplied by the growth rate, with the product being rounded up.
The max day value is 25. Therefore, the max any dinosaur will generate for you is (Dinosaur GRM*25=DNA Value)
In an example, the Mosasaurus has a GRM of 1.5. Therefore, after day 10, the player will earn an additional
10*1.5=15 DNA Icon 15 for surviving day 10.
After day 25 with the Barosaurus, it will start to award the player DNA Icon 75 per-day, the most DNA awarded per day after Day 25, while, for example, with the Tyrannosaurus Rex, with a GRM of 1, on day 25, it will earn a max of DNA Icon 25 per-day and every other day after that DNA Icon 25 because it has a GRM of 1.
Evidently, the Coelacanth and the Megalodon will earn players the least amount of DNA awarded per-day as it has the lowest GRM of 0.1. Therefore after day 25, it will earn
0.1*25=2.5 rounded to DNA Icon 3 per-day.
Length of Time For Creature Growth
In how many days a creature gets elder depends on the growth rate. The formula is: (Growth Rate) × 20 = (days to elder). For example, the Coelacanth has a growth rate of 0.1, and
0.1×20=2, so it takes two in-game days, or 7 minutes, to elder. Although off by a few minutes, the GPM is also about how many hours it takes to elder a dinosaur. A Triceratops with a GPM of 0.8, will take 48 minutes to elder.
