Since I haven’t seen anyone say this, equus have six ‘classes’ based off of their power on mobile. If it’s power is 1.99 or less its in the lazy ‘class’, if it’s power is 2-3.09 it’s in the ‘normal’ class and will not have a special name when born, if it’s power is 3.10-4.50 it’s in the ‘swift’ class, if it’s power is 4.51-6.64 it’s in the ‘maiden’ class, if it’s power is 6.65-13.32 it’s in the ‘racing’ class, and finally, if it’s power is 13.33 above it’s in the ‘thoroughbred’ role. This is a good way to get a guess on a babies power when it’s born.
Don't Listen to people who say that they are waste of time. If are probably used they will be the best early game dino ever and in taming you just have to complete hunt Megapirana task and you will get a 10X smoothing balm and then gather 8 to 10 bushes and you will get 2 carrots then just go and tame it.
BEST THINGS ABOUT THEM IS THAT THEY DO A CONTINUOUS TORPOR DAMAGE WITH THEIR KICK NOT LIKE OTHER CREATURES LIKE PACHY AND SCORPION. AND YOU AND EASILY MAKE NARCOTICS IN THEM SO THEY ARE VERY GOOD FOR TAMING.
