The aberrant versions of this dino require a lot more tranqs than the regular one, took like 15-20 arrows with a 198 damage crossbow to knock out a level 130 aberrant.
Megalosaurus
The megalosaurus is one of the strongest therapods, but its nocturnal sleeping pattern make it significantly less effective during the day. The megalosaurus can bite and even latch onto enemies — including humans — and swing them around, hindering their ability to move. This carnivore is stronger than a Carno or a Rex at night, but during the day, it is much more slow and sluggish.

BE CAREFUL BC THIS GUY CAN EAT UR PT OR ARGY
I was I could pet my tamed Megalos when they’re sleeping during the day…. they are too cute to not pet :(
Don’t wake it up but if you do, use a pistol or assault rifle and shoot it in the face
Fun fact:if you jump on one they wake up. And if you’re on it’s back u live if not opposite.
Bring around 20 stone pillars to trap it just Incase it wakes up on you
I was in Aberration and I saw it right next to my base and I was on my iguanodon and the second it saw me, IT PICKED UP MY WHOLE IGUANODON, luckily my iguanodon does a lot of damage and it was a low level but if that was a high level it would have been over
Use this dino on aberration its always buffed cuz its on a cave and it resist radiation
Be careful around these guys. On Ragnarok, the jungle near Viking bay 2 has them just chilling in the jungle. So be careful when it turns night, as I’ve had one wander down the onto the beach.
Really good for going to the rockdrake den and getting eggs
The best way to tame is make a gate, aggro it on the gate, and when it’s out of stam it’ll knock on its own. Then it won’t wake when it hits night. Trust me, I did it. ^ if this helped.
Beware, when sleeping; they can look like rocks. I dont suggest jumping on them. So before you jump on a „rock” remember to take a good look at it to make sure its not a megalosaurus.
You can find them sleeping in the cave close to the volcano i found three of them
If you see something that looks like a rock but not quite, ignore it. For your own sake ignore it. I ran too close to one and next thing I know me and my parasaur have four on our ass.
Attention epic ARK players, if you place any structure near their aberrant counterpart while they are unconscious they will wake up. If you are making a trap make sure to destroy it after knocking him out.
Watch out they will grab your flyer, throw you off it, and whip the flyer around in the air like a dog with a rag!
Can be used to wreck a Rex. How does a carno sized Dino wreck a Rex? Dunno
First one I ever saw was a lvl 20ish in Hunter Cave. Wiki does not reflect that as a spawn zone.
They look so cute when sleeping!!
So I jumped on the furry rock and landed on its head and it was just spinning and spinning until I got off of its head :>
