Dossier art made by the lovely @Laind004! Common Name: Irritator Species: Irritator familiaris Time: Early Cretaceous Diet: Piscivore Temperament: Curious Wild While the Ark's other spinosaurids are infamous for their high levels of aggression, this couldn't be further from the truth for the pack-dwelling Irritator familiaris. Smaller than the Irritator I'm familiar from the fossil record yet still large compared to most coastal denizens, this social theropod goes about its days roaming the beaches with its familial pack, investigating any other beach dwellers, whether it be a terrified Dodo or a newly awoken survivor. I've even witnessed Irritators go up to and sniff the legs of a Tyrannosaurus without one bit of worry. I believe this seeming lack of fear towards other predators is a product of a natural pheromone emitted by every Irritator that, fitting for its namesake, causes even the largest of animals to steer clear of packs of Irritator. However, newly hatched Irritators, still residing in the pack's den, seem to lack this pheromone, making them choice prey for any predators who are willing to risk the pack's wrath. Domesticated Taming an Irritator is a rather complicated process, as despite their curiosity, they do not form bonds with those outside their pack easily. The most common method I've seen employed involves a mix of playfighting, playing fetch with rare items, and cuddling. The younger the Irritator, the easier it is to domesticate. However, focusing solely on a single pack member may cause the rest of the pack to become jealous or even outright aggressive, shoving the favored Irritator away in an attempt to become the spotlight themselves. Once tamed, an Irritator makes an excellent travel mount both on land and in the sea. Their inherently curious nature makes them excellent at locating rare resources, especially those underwater. Irritator can also be taught to use their pelican-like throat pouch to store large amounts of heavy goods, making them the ultimate companions for gathering expeditions.

Introducing Irritator, The Stealth Spinosaurid Common name: Irritator Species: Irritator Aquafluctus Time: Early Cretaceous Diet: Carnivore / Piscivore Temperament: Opportunist Dossier: Wild: " While walking along the beach I had a surprising sight, an Irritator resting close to the shore, this spinosaurid easily identifiable by its crest and streamlined body is a fast and agile predator, adept at stealthy ambushes and quick pursuits. More than an ambusher the Irritator is an opportunistic specialist in taking advantage of the environment around him, which makes him secure his place near the top of the terrestrial and aquatic food chain. " Domesticated: " Taming an Irritator is not easy, however the tribes that have managed to tame this spinosaurid say it is worth the risk, those who manage to tame this creature are rewarded with a very versatile loyal semi-aquatic companion. With proper training your Irritator can be ridden on battle or used to cross bodies of water quickly, and thanks to its innate agility and impressive capabilities grant its rider the advantage in underwater combat, making it an invaluable mount for both underwater exploration and combat. " Introduction: Hello survivors, all quiet? I hope so, I present The Stealth Spinosaurid, The Irritator. The Irritator is a spinosaurid similar to Baryonyx, it would be a medium spinosaurid being smaller than Spinosaurus but larger than Baryonyx, the main idea is to be a versatile semiaquatic mount playing the role of marine exploration mount in PvE and stealth combat mount or combat support in PvP. Wild: The Irritator is mostly found on beaches and rivers where it spends most of its time resting or hunting. Face to face with a player the Irritator will act peacefully, but it's better not to let your guard down when you're close to him because the Irritator can even be a predator, but above all he's an opportunist and will attack you when you least expect. Like other carnivores, when seriously injured, the Irritator will not hesitate to run away, but before running away, the Irritator will emit a high-pitched roar that will make all nearby creatures angry, making them attack you and will take this opportunity to escape into the water. Taming process: To tame this spinosaurid, you must complete 2 steps: The first step is to drag a fish close to him, as soon as he eats the fish you must be quick and mount him, soon after you mount him he will run towards the water where he will dive in order to drown him. and if that doesn't work he will try to knock you off him and when he tries to do that you must feed him fish meat. As soon as you feed him, the second stage will begin where after he is fed he will calm down allowing you to guide him and when he does that you must hunt fish with him until he is tame. Tamed: Once you've tamed him you don't need a saddle to ride him, however his saddle will be much more useful for those who want to explore the oceans as his saddle has a built in scuba. Once tamed, the Irritator makes the perfect sea exploration mount, being an incredibly fast swimmer and having the strength to take on any sea creature that opposes you and your Irritator, plus out of the water the Irritator can store water in its throat that you can use to attack other creatures or to refresh you and your creatures by granting the hydrated effect to yourself and your allies. Saddle: The Irritator's saddle is unlocked at level 55 with his saddle the Irritator gains a new passive skill "Aqueous Ambush", in addition, the Irritator's saddle has a built-in scuba Description: The Irritator saddle is equipped with an advanced stealth technology that allows the rider to initiate a swift and stealthy aquatic ambush. When activated, the Irritator submerges itself and its rider in water, becoming nearly invisible to enemies above the surface. While submerged, the Irritator's movement speed is significantly increased, and its attacks deal bonus damage upon resurfacing for a surprise strike. Aqueous Ambush: Activation Cost: Moderate amount of stamina Cooldown: 90 seconds Duration: 10 seconds (submerged) The "Aqueous Ambush" ability offers a tactical advantage for hit-and-run tactics and ambushes. Players can use this ability to quickly close the gap between their target while hidden underwater, deliver a powerful strike, and then disappear back below the surface. This ability is particularly useful for surprising enemies, escaping dangerous situations, or dealing a devastating blow in PVP engagements. Effects: - Upon activation, the Irritator and its rider dive underwater, becoming nearly invisible from the surface. - The Irritator will be slowed down while using this skill. - Attacks performed while resurfacing have a bonus damage and inflict a brief disorienting effect on the target. Actions: Left Click: Venomous Bite, Irritators possess a venomous bite that inflicts not only immediate damage but also lingers, dealing continuous harm over time. Furthermore, their bites weaken the stamina of targets, reducing their ability to escape. Hold Right Click: Suction, Irritator uses its suction ability to store water in its throat and then spit it out at its enemies or its allies. (The more oxygen points it has the more water it can store) R: Sniper Mode (Similar to Velonasaur), in this mode the Left Click will now be a shot of a chargeable water projectile that deals damage if carried can cause stun and the Right Click becomes a water jet that deals damage to the player and the mount in addition to having a great knockback. X: Disorienting Screech, by emitting a piercing screech, Irritators can disorient and stun nearby enemies for a brief period, granting themselves and their allies a window of opportunity to strike. C : Tail Spin: The Irritator have a powerful tail spin attack that knocks back and deal damage enemies in a radius around it. This could be particularly effective for dealing with groups of smaller creatures. Ctrl: Fountain, Irritator will fire stored water upwards spraying water in a circular area granting the hydrate bonus to self and allies. (This ability grants the hydrated bonus even to creatures that don't normally have this effect, such as Carnotaurus, Baryonyx, and Tyranosaurus) Passive Skills: - Deals double damage against aquatic creatures such as mantas, plesiosaurus, dunkleosteus and megalodons. - Eating fish will give you increased health regeneration speed (Same as Argentavis buff when eating dead animals) - The more the Irritator runs the faster it will get (Same applies in water) - Has the hydrated effect (Same effect as Spino, Tropical Wyvern and Shadowmane) Increases damage, movement speed and health regeneration. - Irritator have a immunity to Cnidaria and Electrophorus stun. Utility & Scenarios: PvE: The Irritator in this scenario could play the role of a water mount, as it has a high speed of movement in the water and strength enough to face the dangers that the ocean has to offer, in addition its skills with water can help you on land thanks to its ability to hydrate itself with the water it stores in its throat. PvP: In this scenario the Irritator can play the role of Support for allied creatures since its ability to splash water in an area gives its allies the hydrated effect making them faster and cause more damage, besides that it can also serve as turret protecting your base with your water projectiles that can cause stun being excellent against flying creatures being able to knock them down making them subject to attacks on land.

Icthyovenator, Phantom of the Deep Icthyovenator laosensis “Fish Hunter” Early Cretaceous (Aptian), Approx. 125 - 113 MYA Spawns: Red Zone waters, and Green Zone waters. Neutral until hungry A Spinosaurid from Laos with an immense appetite and wonderfully horrific, endless throat pouch to go with it. Wild: As if Baryonyx and Spinosaurus were not able to rule enough of the waterways, Icthyovenator has made its place in the ecosystem right where they have not. These spinosaurids are surprisingly placid compared to their cousin, only becoming aggressive when it comes time to feed. Should something disturb their meal, or something more appetizing show itself, Icthyovenator will quickly change course. Though it isn’t like it needs to do anything in order to catch itself something different. The strange sounds it is able to make can surely lure just about any creature, I’m convinced. Domesticated: If one can brave Valguero's treacherous rivers and overcome the prospect of setting fish into the water for Icthyovenator to snap up, they would find themselves with, probably, the best aquatic mount for traversing the many rivers and lakes of Valguero. The unique properties of the throat sac allow for a wide variety of utilities, including both solidification of liquid elements and condensing of gas! The singing also allows for the gathering of large amounts of fish meat. Combined with Icthyovenator’s speed and power, there’s very little that can challenge this steed in Valguero's deepest depths. Attacks Left click: Bite Hold right click: Start suction R: Change target creature ammo C : Spit X: Start/Stop song Ctrl: Swallow - Bite has a turnaround similar to Sarco. - Bite speed is similar to Carno. - Decent land speed, both walking and running. - Fast underwater but not agile. - Holding C can aim the spit better. Singing The Icthyovenator has a lovely bellow it is able to produce that sounds similar to a tuba mixed with an alligator’s territorial bellow. You can use X in order to start (and stop) this song, which brings you into a minigame much like the Mammoth’s. While playing, the Icthyovenator will start to lure in creatures around it. The better you play, the bigger creatures you can attract! Better songs will also slightly increase the range. When under the effects of the song, creatures become passive as if they were being lured by bee honey. Other details about their singing: - Throat lights up when singing. - Attracts wild fish, making them easier to net, trap, or kill. *Wild Icthyovenators can only lure aquatic creatures. Suction Another feature of Icthyovenator is their suction ability. This goes into their fish-slinging ability later but has other features that could come in handy. When used on fish, manta rays, angler fish, and other small creatures, the Icthyovenator sucks them up and stores them in its gullet, much like a regular fish trap (but without the spoil timer). The size (drag weight) and amount of creatures it can store are dependent on the Icthyo’s own weight stat. The Icthyo can choose to either spit out or swallow any creatures in its throat. If it swallows something with items in its inventory, the items will appear in the Icthyo’s inventory. Other details about their suction: - Can be used on dropped items and bags. - Can be used on many different liquids. - Some items and creatures sucked up can be swallowed (CTRL) for different effects. - Effects for swallowing: — Fish: Healing (similar to Argentavis). — Angler Fish: Gives angler gel. — Water: Hydrated status. — Liquid Element: Solidifies into Element Shards. — Narcotics/Biotoxin: Temporary tranquilizing bite. *Icthyo cannot swallow as many things as it can use for slinging. Effects can easily be added. - Swallowing Trilobites and Eurypterids has a higher drop rate of silica/black pearls from them but gives less Chitin. Fish Slinging Icthyovenator’s offensive capability is not to be shrugged off. With certain items and creatures available, the Icthyo is able to launch them out of its mouth as a projectile. Each projectile has a different effect. - Liquid Element: Projectile that deals DoT when hit with it. - Angler gel: Flammable, glowing puddle. Leaves target glowing. - Fish: Simple projectile. - Manta Ray: Temporary stun. - Water: High knockback projectile. - Nameless Venom: Gives rabies when directly hit, leaves puddles that can lure Rock Drakes. - Gas ball/Gas vent: Suffocating smoke grenade. - Narcotics: Tranquilizing projectile. - Players: Simple projectile. Taming To tame the Icthyovenator sounds like an easy task but, in reality, it is more challenging than you would expect. Simply grab a fish basket filled with delicious fish and wait until the Icthyovenator starts “singing”. Once it starts, release the tamed fish into the water where it is starting to lure other wild fish. The Icthyo will eat the fish and taming will progress! The amount of taming it gives depends on the species and size of the fish you give the Icthyo. Coelacanth gives the least, then Piranha, Sabertooth Salmon, and finally, Anglerfish give the most. Other details about taming: - The Icthyovenator will start to drool just before it’s about to sing so you have time to place the food. - While Icthyo is neutral when it wanders, they grow aggressive during feeding times and will quickly turn on you if you get too close. Ghillie is recommended! - Feeding Icthyo an Anglerfish will leave it glowing and confused, but satisfied! This allows you more time to get away from it.

The massive goose-relative is a force to be reckoned with. Boasting high health, water buff and speed, and a simple passive taming, Diatryma is a perfect early to mid game mount. In real life, Gastornis was a titanic herbivorous bird from Europe. Think dodo and terror bird combined. It had an extremely powerful beak, perhaps for breaking food or fighting off predatory creodonts. DIATRYMA Species: Gastornis parisiensis Time: Early Eocene Diet: Herbivore Temperament: Aggresive Wild These large flightless birds rival even the Therizinosaurs is herbivore ferocity. At a glance, the diatryma cam be confused for the terror bird. However, the diatryma is not only larger and herbivorous, it also seems to show many similarities to ducks and geese. Domesticated These birds are surprisingly effective on the water, where they spend much of their time. They aren't as home in the sea as Pelagornis or Hesperornis, but they can still paddle along at great speeds. On land they are relatively slow and cumbersome. They male for nice tanks though, due to their bulky build. Diatryma beaks are extremely powerful. I've estimated that it could crack a coconut. This is actually not surprising for an herbivore, as ceratopsians possess bone-crushing bites as well. --- In the Wild - Diatryma spawn in around redwoods, coastal waters, and occasionally jungles. In the wild they aggro onto any carnivore that attacks it, and anything from Raptor tier or higher will want to eat this goose. Taming - The diatryma are passive tames, but with a twist; they hate you and want you dead. They have an aggro range slightly larger than a Theri's. When you approach, don't bother with ghillie or crouching. When aggroed onto a player, to will run (or swim) up and preform a set of screeches for about 8 seconds. Only in this time, you can quickly feed it and rereat from its aggro range. To slow, and it will truly aggro and tear you up. When it us ready to feed again it will start stamping its foot (or doing backflips if in water), so keep an eye on it from a safe distance. Process must be repeated until tamed. Riding - Diatryma require saddles to ride. It's saddle is unlocked at level 50. Food - The Diatryma is of course herbivorous. For taming it can take Superior Kibble, crops, or berries. It can harvest corpses when tamed, however. In the Water - After touching water, the Diatryma will get a 30 second Hydration Buff that operates like a Spino's, giving buffs to speed, damage, and health regen. The Diatryma is a speedy water creature, but retains an oxygen bar. Thankfully, it has very high oxygen, so in most cases you won't need to worry about taking this duck for a five. Tank - This creature has average/low speed and turn radius on land. It's high health stat for its tier of creature makes is an ideal tank for fighting enemies from Dilos to Allos; its melee stats are reasonable as well, not pathetic like some tanks. Appearance - The Diatryma is around twice the height of a survivor. It is very bulky as well, a bit like a Theri. In the wild its feathers are usually dull colors like brown, reddish brown, black, or dark grey, with little variation. Their eggs are Medium-sized and are colored blue with black specks. Ants - A hidden ability; the Diatryma deals double damage to Titanomyrma and Rhyniognatha. They are also immune to poisoning from the two.
