Your new favorite renewable source of Chitin, Silica, and Oil
~ Drake on Trilobite

The Trilobite (Try-lo-byt) is one of the creatures in ARK: Survival Evolved.

Basic Info[]


This section is intended to be an exact copy of what the survivor Helena Walker, the author of the dossiers, has written. There may be some discrepancies between this text and the in-game creature.


Trilobite conchadurus


Early Cambrian-Late Permian






Like most Trilobites, Trilobite conchadurus is an opportunistic carnivore that feeds on anything smaller than itself which it can get a hold of. A sluggish creature, the Trilobite's best defense is its incredibly hard shell. This seems to be a common adaptation for the slower creatures of the Island. Trilobite is not a very good source of food. The creature seems to be made mostly out of internal organs and its protective carapace. This is good for the trilobite, as both river and ocean predators are less likely to prey on it if there are better options around.


The Trilobite does not seem to have enough intelligence to be tamed. This doesn't mean it has no use among resourceful survivors, however. Found along beaches and in the ocean's shallows, Trilobites are easily one of the best sources of oil, pearl and chitin on the Island, presuming one doesn't wish to venture into the dangerous caves.


Trilobites can be found in shallow water in small groups, and occasionally on beaches. Trilobites do not fight back when hit, which makes them an easy source of chitin (oil and silica are no longer an easy resource to obtain through this method due to the nerf given to the trilobite in Patch 193.0). When a Trilobite is attacked, nearby Trilobites will attempt to flee.


A Trilobite is a strange arthropod superficially similar to horseshoe crabs. It has a small, flattened body divided into three segments from front to tail; head, thorax and pygidium. It crawls about on many tiny legs, snuffling the sandy sediment for tasty treats. Capable of breathing both air and water, its chitinous exoskeleton protects it from predators.

Color Scheme and Regions[]

X mark

The Trilobite always spawns with the same color scheme and has no color regions.

This means it is currently impossible to make alterations to the Trilobite's colors.


Using a Pick will yield more Raw Meat and Silica Pearls, while a Hatchet will yield more Chitin and Oil. Pearls and Oil are dropped in much smaller quantities than meat and chitin.

This section describes how to fight against the Trilobite.


Trilobites have a slow movement pace, and strangely enough, they can climb any type of mountain, no matter how steep it is! They also do not fight back, so killing them is relatively easy.


Be sure to remember to run after first hitting a Trilobite as they will run quite slowly in another direction! Use melee weapons because they are much more effective on this slow enemy. They will most likely go to the closest water source, so be ready. Standing on them with a Saber and killing/harvesting them seems to work very well as they are pinned in place.


Melee is preferred, as ranged is not practical. Also the Diplocaulus has a x5 damage boost on trilobites and it usually kills trilobites in one hit.


Since trilobites cannot do damage, they cannot pose any threat to players. Be sure you do not follow one into dangerous areas or off cliffs. One fleeing Trilobite may lead the player to a much less-tolerating angry Spino, which frequent the waterways with the Trilobites. Do not get carried away!


They have low health and cannot fight. On occasion, mounts that have crushing abilities will kill them by trotting over them! Most weapons are capable of causing knockback to a Trilobite. If near a water source, use this to your advantage, keeping it from the water where it might escape with its increased swim speed.


Trilobites can be tamed using Fish Basket (Aberration) Fish Basket (Aberration). However, despite the dossier mentioning them as "opportunistic carnivore", tamed trilobites do not eat meat, instead eating berries.



  • Pet: Like any small aquatic creatures, trilobites add life to your base with a pond or any other small water source. They can also go on land too, with no ill effects.
  • Distraction: Has a surprising amount of HP for it's size, but it can't fight back, so use the ample time you have to kill the enemy that's chewing on your Trilobite.


For information pertaining specifically to the real-world Trilobite, see the relevant Wikipedia article.

  • Its generic name translates to "three lobes", while its specific name translates to "hard shell".
  • The Trilobite is the seventh creature added and the third to not have another creature paired with it, the other two being the Spino and Meganuera in that order.
  • The Trilobite has a lot of similarities to the Horseshoe Crab.
  • The Dossier was revealed on the 26th June 2015 on Steam.[1]
  • The Trilobite is perhaps the easiest way to gather Chitin Chitin in the game, besides going into caves.
    • The best way to harvest Chitin and other resources from the Trilobite by far would have to be the Diplocaulus Diplocaulus, which not only applies an extremly large damage multiplier on them, but also harvests them immediately in a similar fashion to the Pelagornis Pelagornis, can swim at high speeds, and collects high amounts of Chitin as well as other resources like Silica Pearls, Oil, and Black Pearls.
  • The Trilobite is also a good way to get Oil Oil and Silica Pearls Silica Pearls without getting deeper in the ocean.
  • As of Patch 193.0, the Trilobite had its shallow water spawn reduced as well as its chances of dropping Oil and Silica Pearls nerfed.
  • Trilobite seem to spawn early in the morning along the coast line. If you're not high enough level to go down to the ocean floor, this is a good place to look.
  • Since the Trilobite is stated in the dossier to be from the Cambrian period, it is the oldest living species on the island, with the previous holder being Pulmonoscorpius, which is stated to have lived in the Silurian period.
  • "Trilobite" is not a real genus name, but a term given to the highly successful and diverse subphylum group, Trilobitomorpha, which encompases all species known as "trilobites". There are thousands of genera of trilobites as of now known to science, all appearing in rock layers dating between 521 - 250 MYA before dying off in the largest extinction event ever to hit the earth, known as the Permian Mass Extinction or, "The Great Dying"..
  • The Trilobite depicted in the game is very similar to Paradoxides. If this is the true identity of the Trilobite seen in ARK, its true scientific name would be Paradoxides conchadurus.
  • Trilobites do not produce Feces Feces.
  • Helena writes that it does not seem like Trilobites have enough intelligence to be tamed. With her saying it doesn't seem that means Helena isn't sure if Trilobites can or can not be tamed. Also Helena saying that the Trilobites don't have enough intelligence means a tamed one won't be of much more use than a luxury pet.
  • The Trilobite along with Coelacanth Coelacanth, Leech Leech, Piranha Piranha and Sabertooth Salmon Sabertooth Salmon became tamable with the Fish Basket (Aberration) Fish Basket (Aberration) introduced in Aberration.
  • Gender of the Trilobites is not assigned in the game, making them unbreedable to players who tame them.


  • When the survivor checks the inventory of their tamed Trilobite, it will have the saddle box alongside the costume box even though the Trilobite is too small to ride.
