1600 base × 15.9 level × 4 × 1.33× alpha kill × 1× server
Official servers use non-1× defaults for kill-type multipliers. Adjust these if your server uses custom Game.ini values.
You can gather Hide, Raw Prime Meat from a Alpha Mosasaur corpse. The corpse has 4,000 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.
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.
