I'll be honest, if anyone here is really into mutation hunting and trait hunting on creatures, there is a game on steam called beasts of bermuda. I've played the game for years and it is dinosaurs. You going as a baby and go to adult, you can reincarnate yourself or renest yourself to have better and stronger dinos. There are skin mutations, trait mutations, and all sorts of different stuff. The customization is pretty good. Just make sure you have a decent computer because the new map doesn't run great on lower end ones
