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.
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.
Do not pause between shots instead shoot the required amount of arrows/darts and wait for it to drop. Make sure you have plenty of narcotics as the torpor on these creatures will drop in the blink of an eye. Can be tamed solo but only with kibble due to the torpor time and can also be carried by a Quetzal if you prefer a taming pen.
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.
Torpor runs out in a minute. Try to wait until just before it wakes up to use all the narcotics needed to get it back to fill torpor. You can the. Relax until the torpor goes back to full. Then it quickly depletes again. Repeat. Starve before you use kibble as its expensive kibble...
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.
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
