Tek Rex

The Tek Rex is the Tek-plated variant of the Rex, added with the ARKaeology event and Extinction Chronicles. It fights like a normal Rex, and a small share of wild Rexes spawn as the Tek version at a higher level.

Where to find it

It replaces a small part of Rex spawns on most maps and is notably frequent on Genesis Part 1. In ASA it is listed on The Island, Ragnarok, Valguero, Genesis Part 1, Astraeos and Extinction. In ASE it also appears on The Center, Scorched Earth, Crystal Isles, Fjordur, Lost Island and Genesis Part 2.

Taming

A knockout tame, done like a regular Rex: tranquilize it from safe cover, then feed meat or kibble. Raw Prime Meat tames faster than regular meat.

Breeding

• Egg: 32 to 34 °C, about 5 hours to hatch.
• Growth: about 3.9 days to mature at 1x.

Uses

• Combat: boss fights, caves and defense, like any Rex.
• Resources: Electronics, Element Dust, Oil and Scrap Metal plus the usual meat and Hide, and a guaranteed Tyrannosaurus Arm.
