I usually find them near lots of rocks
Trilobite

Player-written tips for taming, using, and fighting the Trilobite in ARK: Survival Ascended & Evolved.
If you play on Xbox or PlayStation there breedable so tame two then breed them it’s much easier than spending 100years looking for one! 😀hope this helped
When you incounter a enemi and Ned help bad like a meat shield or damige maker it's god in 8slot of inventory for fast deployment of the trilobite
Use a chainsaw after you kill them for max harvest
These little guys are amazing! In Aberration if you have a Spino and just swim around destroying them they're the absolute easiest/safest way to get oil other than dung beetles.
i think when when you tame these guys they should be shoulder peta
Don’t kill them yet wait until you are up at late-midgame levels before you start trilobite hunting
Are these guys supposed to spawn in water? I only see them in water but today I saw one just chilling on land
There used to be so many on my beach I made a sign and called it “Trilobite Beach”.Then I killed them all and made Chitin armor.The beach is now called “Creature Beach”.
You can find them on herbivore island
I have recently started finding a lot of these on the north West shoreline not recommend for beginners but a very good place to farm for these guys.
If you want to find these guys, go down to south zone 1 I found a shit ton there. Could take a while, but they will gradually show up.
You can find in water as well on beaches. Very fast too!
Was dealing with a rex that spawned in my tribes base with giga.
Saw one and wondered what it was, killed it.
Gave tons of chitin as well as oil and pearls!
I always find multiple of these guys on islands connected to the ocean. They're usually chilling on the shoreline. I personally find it difficult to kill these so I make my pt to do. I once collected 50 Pearls and 100 chitin from one once.
They spawn everywhere and are tamable everywhere not just abberation
This can give you oil if killed then havested
These guys usually spawn anywhere near the beach, I’ve killed around 4 in the same area on the island
I found one on south zone 1, it was in the water
My first one was here in shallow water
