If you want the stuff from their dams...don't tame them cause they won't build any more dams! Like so everyone can see :D

Be warned!! I’ve seen 2-3 of these take on a Spino and kill it!

Do not leave unattended the torpor goes down at a monsterous rate

Strong as hell, especially in packs. Don't put such nice things in your dam if you don't want me to raid it. Jerks.

There is in fact a slot limit! All dinos have 300 slots available

Taming these takes so ‘dam’ long

The method I used to tame was picking up the beaver with my crystal wyvern and dropping it in a taming pen. Pretty easy knockouts but their torpor drop rate is INSANITY and you can't leave then for more than 3 minutes. Feed them either mejoberries or crops (kibble is really expensive but if you want to do that, go for it).

Hope this helps!

A Castoroides can be picked up by a argentavis

You should get a couple tranq Arrows and a crossbow with at least 700 berries, and some narcotics . And BOOM you have Justin beaver ready to get wood.👍

Make sure no other Castoroides are around then bola it and shoot it with tranqs until it knocks out. Make sure you bring loads of bio toxin, because their torpor drains fast. I used this method and tamed one at level 42
