If you, just like me, live on SE mountains and always get your dinos killed by it, all you need is a carno with 7k health (not hard to lv up) and 550% damage, you will be able to bleed to death a lv max one and still have up to 15%/20% health
If you are unsure if a rock is a disguised golem or not, a spyglass shows their name and level even when disguised. Also, when disguised, the rocks often move slightly as you get close, re settling onto the terrain.
If you kill them using a thyla’s gnashed ability then you can harvest their body with an anky. Killed a level 95 and just got 198 stone, 114 Crystal, 134 obsidian, 123 oil, and 78 metal from it. Hope this is useful to someone!! Have a nice day!!! :)
