CreatureVariant

The X-Dunkleosteus is a rare aquatic carnivore variant from Genesis: Part 1, distinguished by its weight-reducing capabilities. It reduces the inventory weight of multiple resources, making it highly effective for resource hauling. This dino is primarily tamed to transport heavy materials efficiently across oceans. It can be airlifted by Quetzal or Tusoteuthis for rapid deployment.
The variant suffers a -3% HP penalty but gains a +5% Melee boost compared to the base Dunkleosteus.

Tame the X-Dunkleosteus using knockout methods. Use a Chain Bola or trap it with a Bear Trap or Large Bear Trap to immobilize it. Sedate with Tranq Arrows from a Bow, Crossbow, or Compound Bow, or use a Longneck Rifle with Tranquilizer Darts.
Feed it Superior Kibble for the fastest taming. Raw Mutton also works if kibble is unavailable. The process takes around 40 minutes and requires no Narcotics. Use the calculator below for your settings.
