As a starter, you may think you won’t need a stone gatherer, such as the Doedicurus, since the Ankylo also mines stone, but, trust me, this fella will make your life a million times easier! Also, they are surprisingly good swimmers!
They no longer harvest obsidian, just stone. Not sure if they changed it with the new patch, but tried to collect obsidian in the Center with him and all I got was stone.
This guy is not only a wonderful stone collector but also a wonderful protector for he of course killed the raptor that was holding me down and I have never had any Dino do that and I had a lot of Dinos
Idk why but the Dode is better than my ank at getting obsidian it needs to be up higher on the list. I get liek 30-40 with it and anky only gets liek 10-12
