For anyone having trouble with these guys (they do but pretty hard), use a bola or argy drop them into a pen. The bola works well for low levels. You will only get about 8 shots off with a snow, so bring extra bola for higher level tames.
Use kibble if you got it, very long tame and as stated, very very fast tupor drop.
Got one last night and he died after a lovely troodon attack...anyway its not fun taming these guys torpor drops ungodly fast so understand while taming him youll be staring at him 90% of the time instead of doing other things. They are unreal with wood gathering mine had 400 weight points and i have a stego with over 600 yet this guy literally carried at least 3x what my stego could. Theyre quick on land and amazingly fast underwater. Ps kibble is a must and you need way more narcos than what this app says i used close to 400 i believe for a lvl 20
If you have an Argentavis, you can grab a wild Castoroides and plop him in a preprepared enclosure near your base. We originally planned to tame him in there.
Turns out, if you don't tame him, he will eventually build a dam inside the enclosure that you can easily harvest from outside the fence. You just have to tranq him afterwards or he will go and destroy the fence.
