On ark mobile ultimate. Upon continues taming trying to get a high level. I have come up to a conclusion that levels and cravings matter. I used a lvl224 bronto around 30k health then impregnate it with a lvl130 rhynio. My baby rhynio(evil orange) comes out to be LEVEL 176.

1st craving : ammonite bile

2nd craving : absorbent substrate (i think,can't remember the name that well)

3rd craving : golden hesperornis egg

4th craving : extraordinary kibble

5th craving : another absorbent substrate

Hope this helps.
