Easily killable with a wyvern. Lightning and poison easiest down to longer range in attack. Just hover above and light it up :) killed my first today and it didn't touch me once. Just remember to watch stamina ;)
I started another game and Spawned in alot of different places and I Spawned where my main game was and I was starting to give up on ark then I got attacked by a sacro and almost died, I don't know what happened next but there were stomps I thought it was a bronto but little did I know a titan Saved me from the sacro then I built an good beginning thatch base and tamed an level 9 dodo and going to tame an Better dino :)
The fastest way for your entire tribe to rage quit is to have one of these randomly spawn in the center of your base. Oh, that doesn't happen? Think again, literally just did. What the actual f*** Ark??!!!
If you aren’t going to tame it, use it for levels. Get a lightning Wyvern to take it down to almost 0 health before you attack with the tame you want to level, and as long as it has enough health you should be able to take it out for stupid amounts of xp
