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.
Once I found a bary onyx right outside of my base and it was fighting a turtle and it didn't make it so I ran in my house but before that I got food and ate them in my hut and hid and now it's outside of my base
2 Baryonyx died during the aquatic war at solo player. One was killed by a Baryonyx while the dead bodies of Megapirhana, 2 Kaprosuchus, and 1 Sarcosuchus float around. The other one was killed by another Baryonyx stunning my Baryonyx in the water and then adding some extras by attracting 3 Cnidaria. A memory that remains in my head.
