Mosasaurus — Background & Lore
The Mosasaurus is the apex predator of ARK's deep oceans. It is huge, tanky and hits hard, and it can wear a platform saddle that turns it into a moving underwater base.
Where to find it
It lives in the deep ocean of most ocean maps in both games: The Island, The Center, Ragnarok, Valguero and Astraeos, plus Crystal Isles, Lost Island and Fjordur in ASE. Each has spawn zones that hold only Mosasaurs.
Taming
A knockout tame. It loses torpor quickly, about 12.8 per second in the ASE files, so bring plenty of narcotics. It also needs a lot of food. Most players use strong tranquilizer weaponry underwater and tame it from a cage or a safe platform. See the taming calculator.
Breeding
A live-birth creature: in ASE gestation takes about 8 hours, and the baby needs about 7.7 days to mature at 1x.
Saddles
The 
Mosasaur Saddle unlocks at level 78, and there is a platform saddle for building on its back.
Tips
Do not tame it alone in open water. Leeds, 
Tusoteuthis and other Mosasaurs often join the fight.
