Be warned these animals are very low on health so use traq darts not arrows. Also try to try to drag them out of the swamp because it's so hard to protect them. Best recommendation is that you bring at least 2000 narcos and you knock it out while having an ally tribe guard you so they don't do damage to your tame. Beware these need to have all eyes on them if you forget or have a moment of hesitation they will wake up and you will waste your expensive quetz kibble. Lower levels are better to tame for eggs cost less kibble but, higher levels are sometimes needed but will cost you dearly if you forget them. Good luck guys and watch your backs in the swamp.
I heard that melee damage increases amount of insulation. Take with a grain of salt, but could be very useful, as you would only need meat to keep them running, and you would need less of these than air conditioners. Again, take with a grain of salt.
You probably think these guys are useless and not worth it but if you tame a few low levels they can be SO useful, as they can incubate eggs. Using them on SE to incubate eggs is really handy because it means you don't have to have a generator that will need to be repaired from time to time.
Dimetrodon kibble is one of the required kibbles for imprinting. However, it can be difficult to see when they lay eggs, as they will be on top of the eggs. To fix this, build a pen and put them all inside. Then, put them all on wander. If you have a male, you can leave him stationary, or neuter him and put him on wander.
These creatures needs alot of narcotics. When knocked out, wait for the torpor to drop. Then force feed narc (1 narc = 40 torpor). The torpor meter will slowly rise and give you time to do other things.
Also remember they need natural water in order to lay eggs. They cannot drown after a patch i belive
