Useful tip, don't lead the allosaurus' into another pack. Right now there is a pack of 15 allosaurus' out the front of my base.

They say beaches are low resource/low threat areas right? WRONG! I used to live in one close to a cold region and some of those decided to run around the beach killing everything there. Fine, I hid from them in my tatch base and once they were far enough I thought I was safe, that until another freaking pack started doing the same. I hid my Dilo (Galinha Punk, my beloved only tame, great companion) inside the base and ran through the ocean to hide on some stones. And this was way before they cold spot me. Result: I had to hold my tears and watch in horror as they destroyed the little base I put on all my effort to build, killed my poor boy and kept going like it was nothing! Their levels were way too high, I couldn't fight them, but I was so sad I tried, died, couldn't respawn there cause I had no bed anymore, and couldn't get my stuff because they were near. Of course i waited until they went away, and of course wild dilos destroyed the rest of my stuff. I shall have my revenge!

These guys usually travel in packs near the mountains, so if you find one, good luck escaping, these guys catch up to you always. Unless you have a bird or a very quick tame, you’re toast.

Pro tip:NEVER start on north zone 1 on mobile! I saw one of these dudes on the beach along with 2 argys and a scorpion and a spino in the water. So only start there if you think, that you can take some challenge.

These guys are everywhere in Valguero. My friend and I were gathering resources when I saw them I ran and remembered Ark's loading screen had a tip that said "You don't have to run faster then the dinos you just have to run faster then your friend" so I used my bola in my hotbar and got my friend. Moral of the story get bolas lots of them

I always encounter these in pack with their step bro Rex

Don't run. You can't.

These things can be a real pain early on. My brother and I had just started on Valgaro and we where doing good. We had a nice house with a great view of the river, a breeding pair of raptors and a bunch of other various animals. Life was good. one day we decided to explore the other side of the river. At first everything seemed fine, but then on our way back we saw them, two allosauruses blocking our home. We tried to sneak past but they saw us and chased us all the way home. Suddenly they turned and we thought we were safe. But then we saw why they turned. They had found our beloved pets and were attacking them. The battle was fierce and it looked like we might when win. But then one by one our pets showed up in the death chat until only our raptors where left, the prize of our position. By now one of the allosaurus had died and there was just one left. But that one was to much and we lost everything. moral of the story run away from your hour not towards.
