More about taming the Mosasaurus
Mosasaurus must be knocked out before taming. The best food is Exceptional Kibble, which provides the fastest taming time. Raw Mutton also works well for players without access to kibble.
Use a Bow or Crossbow with Tranq Arrows to sedate it. About 46 units of Exceptional Kibble are needed. The taming process takes around 73 minutes and requires approximately 434 Narcotics. Use the calculator below for your settings.

Combat notes
Mosasaurus has a strong weakness to SpikeWall damage, taking +400% more damage. This makes spike walls extremely effective in defensive perimeters. It also takes +120% more damage from Instant HurtDinos and +55% more from Melee DmgMetal RaidDino attacks. Avoid using Mining Drill Harvest, as it deals no damage to this creature.
The Mosasaurus has a head hitbox that takes 1.5× damage, making headshots effective for faster knockouts. Focus on the head when sedating.
Can break Thatch and Wood. Build at least in Stone.
