Never ever ever take one of these guys on with a pteranadon even if your friend tells you to. These Dino's can knock you off your mount and stun you for ten seconds, this is no dillo blinding attack when stunned you cannot do anything at all except watch him eat you and your dino.
When I was a noobie in Ark I saw this guy. Like the therizinosaur incident with me thinking this guy is passive I walked up to him while he was busy dealing three raptors. He slew the raptors easily then he drew his attention to me. I was like “Hello there” and he was like “Omae wa, mou shindeiru.” He stunned and easily killed me. Lesson learned. Don’t ever, ever go near creatures dealing with other hostiles. You might save your character by doing this.
NEVER and I mean NEVER FIGHT IN WATER. They will stun and all you can do is wait as you see this thing kill your lv 132 triceratops. That has killed rexs. Rip Trixie the triceratops Jan 2020- Mar 2020.
So there was one of these guys near my house, I was worried that it’s gonna attack my house someday. So I decided to tame a few dilos (21 if you must know) and took him out. Man didn’t even get the chance to fight back (I didn’t go in and attack him, I target whistled) (He wasn’t in the water at that time)
If you ever see one alone, get the heck out of there. It will kill your friends, your family, and everyone you ever met. Including you. I had a shotgun. And I killed one. Then sometime later, a Baryonyx comes and eats my Tapejara, my raptor pack, my rex, and most of my thatch home (Don't ask) I ended that Baryonyx with my trusty shotgun I named Cal.
