Trilobite conchadurus is a species of trilobites indigenous to ARK Island. They are the most ancient species found on the ARK Island, having originated between the Early Cambrian to the Late Permian (252 to 541 mya). The next most ancient species found in the area is the Pulmonoscorpius gigantus, originating from the Silurian Period (443.8–419.2 mya).


T. conchadurus is an arthropod related to horseshoe crabs. Their bodies are laterally compressed and divided into multiple armored segments. Spines extending from their carapace make them somewhat more difficult to consume by smaller would-be predators. Their tail is also likely used for defense but is considered harmless towards Humans. They possess many tiny legs that are used both for movement as well as for snuffling through the sand for any organic material small enough for them to consume. Amphibious by nature, they are capable of breathing both air and water.

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 defensive 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 doesn't have its uses among resourceful survivors, though. Trilobites are easily one of the best sources of high quality chitin on the island, assuming one doesn't wish to venture into the dangerous caves.


T. conchadurus are naturally found in shallow water, occasionally emerging onto beaches early in the morning to feed. Later throughout the day they will return to the ocean floor, which is safer for them.

Although harmless to larger creatures such as Humans, t. conchadurus are largely aquatic creatures but thanks to their multitude of sharp legs are able to climb natural surface areas, no matter how steep. When attacked, a t. conchadurus and any nearby conchadurus will attempt to flee in any direction it/they can, including these steep surfaces; however they will most often flee towards the closest source of water, where they are the most comfortable.

Relation to HumansEdit

Trilobite (ARK)

Survival dossier on Trilobites.

Although Humans are not indigenous to the ARK Island, they are still found there, having been brought to the island via mysterious means. Over the millennia they have been harvested for various materials. In days past, they were used to harvest oil and silica pearls, although over time they have apparently evolved to no longer produce such ample amounts of the substance. They are still occasionally harvested for raw meat - albeit for small amounts of it as a conchadurus is mostly viscera - and they are an easy source of chitin. Those seeking raw meat or silica pearls are inclined to use picks while those seeking chitin and oil ought to use hatchets.

Those that have domesticated a Smilodon brutalis may stand upon a trilobite to prevent it from moving under the creature's heavy foot, pinning them. From here they can be more easily slain. They may also be crushed under larger mounts.

Trilobite hunters must remember that conchadurus is surprisingly fast. While ranged weapons can be used in a pinch, they are considered impractical and melee tools are the preferred method of dispatching them. They will usually flee towards the nearest water source and so the hunter ought to be prepared for submerging in water. Another danger of hunting the conchadurus is that they may flee into dangerous areas; some former survivors have been recorded as having fallen off of cliffs in pursuit of a trilobite, and more than once a survivor has been inadvertently led into the jaws of a Spinosaurus aquareliga.
