Late Jurassic - Mid CretaceousDiet
Usually found in the deepest parts of the water around the island, Amonitina multiamicus has a strange relationship with the other creatures of the deep. It must do something beneficial for them since every nearby sea creature defends Ammonitina when it is attacked. What this distinct symbiosis is based on, alas, I have not yet discovered. Ammonitina has also made its way into the deeper parts of many underwater caves. Even within these caves, the creature will draw attention if assaulted, making harvesting its resource-rich shell a tricky proposition, depending on what other dangers may be lurking nearby.
Like many of the untameable ocean dwellers, Ammonitina still has enough utility to be a valuable hunting target. If a tribe is willing to risk the wrath of nearby would-be protectors, Ammonitina bile can be harvested from the innards of its corpse. This bile can then be worked over with other chemicals to produce powerful concoctions, the most notable being a mixture that causes creatures to become enraged and attack the source of the scent.
Unlike the majority of animals in the ocean, the Ammonite is a passive animal that won't fight back. However, when attacked, it will release a green, inky substance into the water, causing all wild animals nearby to become aggressive; including nearby land animals.
The Ammonite resembles a Nautilus, but much bigger, comparable in size to some of the largest of fossil species, bearing 10 tentacles and a large spiral shell. The mouth is vertically orientated with teeth.
Color Scheme and Regions
This section displays the Ammonite's natural colors and regions. For demonstration, the regions below are colored red over an albino Ammonite. The colored squares shown underneath each region's description are the colors that the Ammonite will randomly spawn with to provide an overall range of its natural color scheme. Hover your cursor over a color to display its name and ID.
This information can be used to alter the Ammonite's regions by entering
cheat SetTargetDinoColor <ColorRegion> <ColorID> in the cheat console. For instance,
cheat SetTargetDinoColor 0 6 would color the Ammonite's "shell" magenta.

This section describes how to fight against the Ammonite.
The Ammonite is a non-aggressive animal that will not attack the player on sight.
The shell of the Ammonite is tough and resilient against most weapons. Therefore, players should target the tentacled head, which is vulnerable to damage.
A Pike is the best used for close quarters, as the weak area is quite small and hard to aim with a crossbow or rifle. It is also recommended to kill all wild animals nearby, as these will become hostile when you attack the Ammonites.
The Ammonite itself is not a danger, however, when attacked it will release a green substance into the waters, causing nearby wildlife to become aggressive for a whole minute. An Ammonite hunt can quickly become overwhelmed by masses of normally passive animals. Its rage effect will last for 60 seconds. Also, the underwater caverns and depths Ammonites dwell in have their own dangers, such as mass shoals of Cnidaria, as well as many other terrors of the deep.
The Ammonite will not fight back in any way, making for a rather easy kill so long as there are no other animals nearby.
- Resources: The Ammonite can not be tamed but does provided plenty of resources lincluding Ammonite Bile, Black Pearls, Chitin, Oil and Silica Pearls, which are all valuable for manufacturing, fabrication, and crafting various items that use these materials. Specifcally, the Pheromone Dart is made with Ammonite Bile, which can be used to make any wild creature aggressive to a targeted creature or survivor that is hit.
- Enraging Wild Dinos: Though it is often unfavorable to attract much of the deep sea or cave predators toward you when attacking an Ammonite, it could possibly be useful in specific situations of underwater ambush or escape.
- Taming assistance: Their rage ability can be an annoyance but is perfect for drawing the attention of rare animals for taming to safe locations.

- Dossier revealed on December 21, 2015 
- Be wary if you do try to kill and harvest an Ammonite, as the Rage effect lasts for an entire 1 minute.
- By far the best way to kill and harvest an Ammonite is with a Baryonyx, as when it uses its tail spin, it does not actually aggro the Ammonite and thus no call for help for other creatures to come attack you.
- The name Ammonitina multiamicus is most likely a reference to its behaviour. Multi being the Latin-root word used to describe anything of number, greater than one, and Amicus being the Latin word for "friend", would roughly translate the name to "Ammonite with multiple friends". This is most likely a reference to the symbiotic species is shares with all deep-sea creatures in that it can aggravate all nearby creatures (its "friends") onto the attacking player for protection. It is unknown if the symbiotic relationship is commensalist(being a relation where one organisms benefits but the other is mostly unaffected), or mutualistic(being a relation where both organisms benefit from one another), as the Ammonite could be providing something in return for its protection from even the fiercest of aquatic predators, or swaying deep-sea protectors by using their Ammonite Bile without giving anything in return. As Helena states in the dossier, the nature of this relationship between Ammonite and the oceanic creatures is unknown.
- The top right image in the dossier appears to have an Arthropluera.
- Contrary to popular belief, they are not only found in caves. Similar to Eurypterids, clusters of ammonites can be seen on the seafloor in various parts of the map, such as the South-West corner. Some have been seen past the giant rock spires of the south.
- The diet of the Ammonite in the dossier is stated to be 'Bottom-Feeder', which could definitely be a plausible diet for a deep-sea cephalopod, but except for evidence being found that aptychophoran ammonites probably fed on plankton, there is a huge lack of information on the general diets of most ammonite species due to rarity of soft tissue being fossilized.
- Ammonitina is not a real genus name, but rather the name of a suborder of ammonites. The ammonite depicted in Ark is very similar to Parapuzosia seppenradensis in size; if this is the true identity of the ammonite seen in the game, its true scientific name would be Parapuzosia multiamicus.
