I consider myself lucky to have encountered Carcharodontosaurus medicupestis and survived to tell the tale. While I'm not sure if this predator grows larger than a Giganotosaurus, I hope I never find out. A single one of these powerhouses held its own against an entire army of us, and that encounter cost us dearly.
 
The Carcharodontosaurus can sweep attackers aside with its tail, but it's the other end you should really be wary of. It has teeth like steak knives stuck in a jaw strong enough to shred most prey. Even a near miss will shred you, but good.
 

With the latest patch from Wildcard, the bug that a dedicated ARK server crashes with a map size (savefile) of 4GB is finally fixed! The other patch notes are:

Dragon was vanilla. 19 Rexes and 1 Yuti. Rexe had between 28k and 32k HP and Damage was at 600-800. Saddles we had the first half simple 60-80s and the rest then 130-180s values. 4 Rexes died. Luck had that the Dragon could not fly off and I have very (too) late with the Yuti "screamed". Players we were two and the one has shot with Shotgun and Minigun.

Fjordur will be a free, official, non-canon DLC expansion map coming to ARK: Survival Evolved on June 12, 2022. Expected "features" from the new map:

New animal that will be released in June 2022 with the new DLC map Fjordur:

Even with all the other monstrosities here, this fugitive from a Creature Double feature deserves first place. I mean, Dracula is already in the name of his species! And Desmodus has a scream that he can use to scare pretty much anything that gets in his way. He's also smart enough to limit himself to victims he can kidnap into the night.

Andrewsarchus is making its way to Fjordur, and it has a whole arsenal of tools with it!  Andrewsarchus may seem sluggish when foraging, but they can be unexpectedly fast when provoked. Once he's tamed, you can attach a minigun to his saddle!
