Drops & Harvest Resources

You can gather Hide, Raw Meat, Raw Prime Meat from a Rex corpse. The corpse has 520 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.

60%~24~17 hits40%~16~13 hits
3%~1~17 hits2%~1~13 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.
