Mosasaurus
Mosasaurus Overview
In ARK: Survival Ascended, Mosasaurus occupies the aquatic utility niche - is a versatile aquatic mount for underwater exploration and resource gathering. As a carnivore, it responds to knockout taming - favoring Exceptional Kibble - and ships with 1300 base Weight, providing massive inventory space. It gives live birth after a gestation period, with offspring maturing at a glacially slow pace - plan for a multi-day commitment. Survivors lean on it to gather Hide, Raw Prime Meat at much higher rates than hand tools. That combination of survivability and damage is why Mosasaurus sits on most endgame mount shortlists.

Drops & Harvest Resources
Harvesting a dead Mosasaurus yields Hide, Raw Prime Meat. The corpse has 2,000 harvest health, allowing multiple hits before it's fully depleted.
Different tools yield different quantities - check the table below to pick the right tool for the resource you need. Generally, a Pick favors meat while a Hatchet favors hide and secondary materials.
| Resource |  Pick |  Hatchet |
|---|---|---|
| 40%~82~63 hits | 60%~123~50 hits | |
| 4%~4~63 hits | 4%~4~50 hits |
Estimates based on game-extracted data (weights, quantities, harvest multipliers, damage type chains). Each harvest event independently rolls each resource - higher weight = higher drop chance. Actual yields vary with RNG.
