The Mosasaurus (moze-uh-sore-us) is one of the Creatures in ARK: Survival Evolved.
Basic Info
Dossier
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.
- Wild
Until recently, I believed the Ultramegalodon 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 deep waters off the island. Growing up to 50 feet long, Mosasaurus is larger than almost every other aquatic creature I've encountered thus far.
- Known Information
Contrary to common belief, Mosasaurus cannot breathe underwater. Rather, it can hold its breath an incredibly long period of time, similar to a whale. Mosasaurus is a deep-sea marine lizard, not a fish. It spends most of its time in the deeps, and only comes up to surface to breathe, or chase prey with an engulfing chomp.
- Domesticated
Despite its power, Mosasaurus is not ideal for all deep-water activities. Its slower swim speed makes the risk of drowning much higher when using Tylosaurus to reach oil deposits or silica pearls. Having one with you as an escort, on the other hand, is probably the best oceanic defense available!
Behavior
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
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.
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.
This information can be used to alter the Mosasaurus's regions by entering cheat SetTargetDinoColor <ColorRegion> <ColorID> in the cheat console. For instance, cheat SetTargetDinoColor 0 6 would color the Mosasaurus's "body" magenta.

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.[1]
The stat-calculator does not work in the mobile-view, see here for alternatives: Apps
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.

Preferred Food
KO Strategy
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.
Combat
This section describes how to fight against the Mosasaurus.
General
The Mosasaurus has the 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 hone 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.
Strategy
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
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
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
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
Roles
- 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)

Notes/Trivia
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, Ichthyossauruses 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. Length wise, the Predator X (Pliosaurus funkei, recently found pliosaur partial fossil) was estimated to be equal to it, but lacking the trademark paddle-like tail mosasaurs have, its size is meant to belong to a much more robust marine reptile. If one were to use its body size as the base for models, it could almost match the game size of Mosas, but would still be smaller.
- The Dossier was revealed on 06/13/2015 [2]
- 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[3] 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 size to an Ichthy to a Megalodon. A much larger creature is behind the Megalodon, which could be a Mosasaurus or a hinted-at underwater boss.
