Lost Therizinosaur
Variant
Overview
The Lost Therizinosaur is a large herbivore variant with a unique gathering specialization. It excels at harvesting a wide variety of resources, particularly Berries, Wood, and Seeds, with high efficiency across multiple attack types. This dino is primarily used for automated and rapid node farming in dangerous or hard-to-reach areas. It can be airlifted by Quetzal or Tusoteuthis for fast deployment.
Its compact size and carryable status make it ideal for transport in large-scale farming operations where speed and efficiency are critical.

Drops & Harvest Resources
Killing the Lost Therizinosaur yields Therizino Claws, Hide, Raw Meat, Raw Prime Meat, and Keratin. The Hatchet provides the highest yield for Hide and Keratin, while the Pick maximizes Raw Meat and Raw Prime Meat.
| Resource |  Pick |  Hatchet |
|---|---|---|
| 40%~15~12 hits | 60%~22~9 hits | |
| 60%~17~12 hits | 40%~11~9 hits | |
| 3%~1~12 hits | 2%~0~9 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.
Gathering Abilities
The ClawAttack, ClawHarvest, and BiteHarvest attacks gather resources with a 10× multiplier on Berries, Crop Seeds, Mejoberry, Mejoberry Seed, Mushroom, Narcoberry, Narcoberry Seed, Plant Species X Seed, Plant Species Y Seed, Rare Flower, Rare Mushroom, Stimberry, Stimberry Seed, and Wood. Cactus Sap and Fiber are gathered at 8× efficiency. This makes the Lost Therizinosaur one of the most efficient herbivore gatherers for seeds, berries, and fiber-based resources.
Damage Resistances
The Lost Therizinosaur has a strong weakness to Instant HurtDinos, taking +120% more damage, and is highly vulnerable to SpikeWall traps, which deal +100% damage. It is highly resistant to fire, taking 60% less damage from fire-based attacks. Melee attacks with impact effects are also 50% less effective. Exploiting its weaknesses with spike walls or instant-damage mechanics is highly effective.
