Basic Info[edit | edit source]
Dossier[edit | edit source]
Until recently, I believed the Megalodon to be the greatest of the ocean predators. Then I discovered Mosasaurus suspirita in the deeps. Not quite as fast, but much larger and stronger, the Mosasaurus rules the darkest waters off the Island. Growing up to 50 feet long, Mosasaurus is larger than almost every other aquatic creature I've encountered thus far.
Mosasaurus is a deep-sea marine lizard which spends all of its time far beneath the water's surface. It is without a doubt one of the most fearsome creatures of the Island, and can certainly be considered among the ocean's apex predators.
Mosasaur has proven to be an excellent tame for the most advanced tribes. Due to its sheer size and power, you will often find tribes with bases and defenses built upon a Mosasaur's large "platform" saddle.
Having one with you as an escort is probably one of the best oceanic defenses available!
Behavior[edit | edit source]
The Mosasaurus is found deep in the ocean and can be quite far from the shore. It often resides towards the edge of the map boundary, and can be surprisingly elusive. It behaves similar to the Plesiosaur. Mosasaurus has a fairly average aggro radius, and will pursue the player a fair distance horizontally. However, it will not follow the player into shallow water, much like the Plesiosaur. It also is not necessarily found near cave entrances like a Plesiosaur.
Appearance[edit | edit source]
An enormous marine lizard, Mosasaurus is one of the largest creatures found in the waters surrounding the island. It has four flippers to propel its massive body through the seas. A small, finned ridge runs down the length of its back before developing into a paddle-like tail. The solitary and territorial Mosasaur is fairly slow-moving, but with its size, it can cover more ground than one might expect, making them adept ambush predators that strike from below to inflict crippling wounds.
Color Scheme and Regions
This section displays the Mosasaurus's natural colors and regions. For demonstration, the regions below are colored red over an albino Mosasaurus. The colored squares shown underneath each region's description are the colors that the Mosasaurus 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.
Server admins can use this region information in the Console Command "cheat SetTargetDinoColor <ColorRegion> <ColorID>".
For example, "cheat SetTargetDinoColor 0 6" would color the Mosasaurus's "body" magenta.
Region 1 is not used
Region 3 is not used

Base Stats and Growth[edit | edit source]
Note that creatures will have different stats in Survival of the Fittest
|Attribute||Amount at Level 1||Increase per point||Taming Bonus|
1Percentages are based on the value of the stat the moment the creature was tamed (after taming effectiveness)
2The absolute Base Damage is shown here instead of the percentage.
3Wild creatures do not level up movement speed
4Torpidity increases every level on wild creatures, but can not be increased once they are tamed.
5The Mosasaurus is incapable of drowning.
|Movement Type||Base Speed||Sprinting|
- These are the base speeds of the creature at 100% Movement Speed
- For a comparison of the speeds of all creatures, see Base Creature Speeds
Wild Stats Level-up
Type in values of a wild creature to see on which stats it's emphasized. Green values on a high-level creature are very good for breeding. If you have already tamed your creature you can try to recover the breeding-stats with an external tool.
Note that after the creature is tamed it gets bonuses on some stats depending on the taming effectiveness. This makes it hard to retrieve the levels on a tamed creature, so this tool is only for wild ones, but gives a first impression, how well the stats are distributed.
Taming[edit | edit source]
For general infos about domesticating a wild creature see Taming.
KO Strategy[edit | edit source]
One strategy would be using a Plesiosaur to find one and lure it into a water cave and shoot arrows/darts at it there. They also seem to follow a similar AI as that of the Plesiosaur and be tamed in a similar way. They don't seem to want to go too high above a certain depth and dive back once they reach it, allowing a person to hit them with arrows to aggro, swim up, and then break aggro. Repeat and it should be knocked out. Remember that the bow/slingshot cannot be used under water so a crossbow is required. I have also noticed that if you have decent movement speed (120%-130%) and flippers, it is very easy to kite a Mosasaurus because of its large turning radius.
Taming a Mosasaur requires the largest amount of food of any carnivore creature in the game, much more than a Quetzal and more than double the amount of any other Apex Predator, including the Giganotosaurus. However, like some other end-game creatures, they can starve all the way down their taming process, giving enough time to gather the meat needed in the moment, but be sure to wait until the torpor level drops and feed narcotics or narcoberries in bulk to keep the Torpor level rising till the max before starting to fall again. Their consumption speed also assures that no meat will be wasted, as long as the newest meats keep being added to the last slots.
It can also be grabbed using a Tusoteuthis, and the torpor from the grab will eventually knock it out. This will, however, take a very long time. The process can be made faster by shooting it with a tranquilizer arrows from a crossbow, or dragging it close enough to the shore where it can be shot with more powerful tranquilizers. Be careful not to drag it too close to the shore or out of the water however, or it will die.

Preferred Food[edit | edit source]
Combat[edit | edit source]
This section describes how to fight against the Mosasaurus.
General[edit | edit source]
The Mosasaurus has the second highest health and damage stat of any aquatic creature. If you encounter one unprepared it is recommended to stay away or swim closer to the surface. If a confrontation is desired or inevitable, make sure that you can focus solely on the Mosasaurus. These creatures live in the deepest parts of the ocean, so it is very common for other creatures to confront the player at the same time. Ichtys can sometimes mob the player without a trace of their location, but they are not nearly as aggressive as Megalodons, which sniff out the player from far away and home in when blood is spilled. Anglers and Mantas patrol the waters, adding more problems to the unprepared player. If the battle is taking place next to a sea cave, the player will almost certainly be dealing with two to three Plesiosaurs. As always, multiple Mosasaurs can also cause a problem.
Player movement speed needs to be at least 206.5% to outswim it while wearing SCUBA Flippers or 181% while wearing SCUBA Flippers AND consuming a Focal Chili.
Strategy[edit | edit source]
The Mosasaurus is very tanky, and it will take a lot of damage while also dealing a lot in return. If you have a very strong Megalodon or Plesiosaur, you will not have too much trouble taking it down. If you don't have a strong creature, you can lure it to an underwater cave and shoot it with a crossbow, as it cannot fit inside. Be sure the Plesiosaurs nearby don't get the better of you!
Weaponry[edit | edit source]
A crossbow is the most effective weapon to take down a Mosasaurus, but only as a last resort. The best strategy is to use a combat trained dinosaur such as a Plesiosaur, or simply avoid them. They are humongous, but their dark coloration can take a player by surprise in the dark ocean depths.
Dangers[edit | edit source]
Again, it does possess the highest health of any aquatic creature and has 100 base damage, only surpassed by the Alpha Rex and Giganotosaurus. A Mosasaurus can kill a player within seconds if it manages to catch you off guard. Do not get too distracted with Deep Sea Loot Crates, or taming creatures. Other animals like the Mosasaur can ruin such indulgences.
Weakness[edit | edit source]
While very bulky in both HP and strength it can't turn very fast making fast Megalodons very useful. Luring it to an underwater cave and shooting it is an easy way to kill it as it cannot fit inside.
Utility[edit | edit source]
Roles[edit | edit source]
- Mobile Base Platform: The platform saddle can be used to build a mobile aquatic base. Structures do not affect Dinosaur weight capacity, but storage does; increase weight if used for transport. (Level up weight, Speed, and Stamina)
- Warship: Mosasaurus has high health and damage, which makes it useful in battle. The platform saddle also allows for cannons and siege weapons, allowing for naval warfare. (Level up Health and Damage)
- Aquatic Tank Having a base health equal to the Alpha Raptor, the Mosasaurus can take massive damage, second only to the Giganotosaurus (Level Health and Melee Damage).
- Oil Rig: Due to the fact the Mosasaurus can carry a large amount of weight, you can make it built for collecting enormous amounts of oil and converting it to gasoline. While not an ideal or recommended use, you could also use it for collecting crystal as well. (Level up Weight, Damage and Health)
- Bio Toxin Gatherer: Unlike most aquatic creatures, tamed Mosasauri do not attract Cnidariae. Additionally, due to how group aggro mechanics work, other Cnidariae won't turn against your Mosasaurus if they are killed in a single attack. This makes the Mosasaurus an ideal creature for safely wiping out swarms of jellies and for gathering their Bio Toxin, as long as the damage dealt is high enough to kill them in one hit. (Level up Melee Damage)

Notes/Trivia[edit | edit source]
For information pertaining specifically to the real-world Mosasaurus, see the relevant Wikipedia article
- It regenerates stamina while moving as fast as when standing still.
- Like other aquatic/amphibious animals it has no oxygen stat, despite it being mentioned as breathing air in the dossier.
- Despite what the dossier says, a tamed Mosasaurus is anything but slow, and under no circumstances slower than Megalodons. In fact, Ichthyosauruses or Mantas with high movement speed stats are much faster, but by the level a player can afford to tame a Mosasaur with relative safety (60+), oxygen is probably not a concern. Not to mention that the first saddle only unlocks at level 75, same as the scuba gear set (which excluding the leggings is extremely cheap). This, combined with high combat capabilities, make the Mosas and fellow Plesios ideal for deep sea exploration. Instead, Ichthies and Mantas are best used to farm silica pearls and Deep Sea Loot Crates. Megalodons, however, have a faster turning speed and are found in abundance across the seas of ARK, making them the "water alternative" to Direwolves.
- In the Dossier it mentions Tylosaurus, another genus of mosasaur. It's possible this could mean that Tylosaurus will be added to the game as a smaller, faster alternative to the Mosasaurus. However,the way Tylosaurus is used in the sentence suggests that the author might simply be mistakenly using the names Mosasaurus and Tylosaurus interchangeably.
- ARK's marine beast is much larger than any know mosasaurus. The actual description is correct, but the in-game creature is much larger than 50 ft.
- The Dossier was revealed on 06/13/2015 
- The dossier mentions in the 'Wild' section that the Mosasaurus is larger than almost every other aquatic creature, thus stating the existence of a larger marine creature. This is likely the '4th boss' that was referred to in ARK Digest 18 or the Leedsichthys.
- The Mosasaurus is actually not a fish, but an aquatic lizard, which means that an actual Mosasaurus cannot breathe underwater, it can only hold its breath for an incredibly large amount of time.
- The Mosasaurus cannot be rendered unconscious with a Bow/Slingshot/Longneck because they do not work underwater, unless you lure it to a cave and KO it.
- A disturbingly large creature is shown in the Ichthy dossier where it compares the size of an Ichthy to a Megalodon. A much larger mosasaurus than normal is behind the Megalodon, possibly hinting at a new underwater mosasaurus boss.
