CreatureVariant

The Aberrant Iguanodon is a rare herbivore variant found in bio-zones, caves, and fertile areas. It excels at gathering a wide variety of plant-based resources while being ridden. It can be airlifted by Argentavis, Karkinos, Megalosaurus, Quetzal, or Tusoteuthis for fast deployment across difficult terrain.

Taming requires a knockout method. Use a Bola, Bear Trap, or Plant Species Y to immobilize it. Then use Tranq Arrows from a Bow or Crossbow, or Tranquilizer Darts from a Longneck Rifle to sedate it. Feed it Simple Kibble for the fastest taming. About 15 pieces of Simple Kibble are needed. The process takes around 13 minutes with no Narcotics required. Use the calculator below for your settings.
