I believed Sarchosuchus was the largest Crocodilian on the Island, until I encountered Deinosuchus. Massive and bulky, this specimen seems to actually be a mix of its' namesake, and a similar species known as Purussaurus.
Deinosuchus sport huge and powerful jaws, which they utilize to break the bones of their prey, and halt their escape. Attempting to escape while suffering the effects of their bite can lead to your demise. This coupled with their incredibly tough hide can make disposing of Deinosuchus a difficult and dangerous task.
Domesticated
When tamed, Deinosuchus can make quick work of many creatures, both land and water. Most creatures seem to lack the intelligence to halt their movement when suffering the destructive effects of a Deinosuchus bite, and this ultimately costs them their life. Any tribe in control of a Deinosuchus packs a dangerous punch...or in this case...bite!

Appearance
The Deinosuchus is a large crocodilian with a resemblance to the Sarco. However, the Deinosuchus is bulkier and its jaws are more broad.

Behavior
The Deinosuchus generally tends to swim around swamps, rivers, and oceans, waiting for prey to get within striking range.
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]
Deinosuchus
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.
If the rider aims with the camera at the sides or at the back of the mount and attacks the Deinosuchus will turn to that direction and bites, needs at least 90° degrees.
Can be used every 0.45s by both a rider and the AI.
The Deinosuchus has two different modes while swimming:
Surface Swimming: The Deinosuchus will swim similar to a Raft, only swimming on the water surface without diving. To deactivate this mode swim down using the crouch button (C, , , ).
Free Swimming: The Deinosuchus will swim normally as a native aquatic creature. To deactivate this mode swim up until reach the water surface.
Piranha Scarer
The Deinosuchus scares Piranhas when it is swimming.
Damage Reduction
The Deinosuchus reduces all kind of damage by 50% that it receives on its head.
Also the Deinosuchus' body reduces the incoming damage depending on the type of damage that it is receiving, and all those multipliers are stackable with the head multiplier:
This section describes how to fight against the Deinosuchus.
General
Deinosuchus has a low detection range around it, so its relatively easy to avoid direct conflict with it, however once the player got its attention there are some thing to consider if the player wants to kill it.
Strategy
Deinosuchus are more vulnerable on land than in water, so luring one to shore will allow for it to be defeated more easily. If it receives damage on its head it receive 50% reduction for all kind of damage, so its recomended to focus on attack the rest of the body.
Weaponry
Most of the ranged weapons that use arrows such as Bow, Crossbow or Compound Bow are not recommended because of the massive damage reduction that the Deinosuchus have against this type of prejectiles, going melee on foot is not viable either because of the same reason. If the player goes on foot the best strategy to take it down are specific firearms such as both types of Shotguns, Longneck Rifle or Fabricated Sniper Rifle because those weapon's damage are not reduced by the Deinosuchus' skin. (See Passives for more details)
Dangers
Although Deinosuchus may seem cumbersome on land, it excels in speed once it enters the water. This speed allows a Deinosuchus to make quick work of smaller creatures. It's Chomp attack can do upwards of 425 damage and inflict a Fractured effect that does damage on a moving target.
Weakness
Since Deinosuchus are much slower on land, a ranged weapon can be useful to take one down.
Passive Tame: When it is basking with its mouth open, run up and put food in its mouth, Superior Kibble prefered. Ghillie suit makes this much easier but you still must avoid getting too close.
Utility
Roles
Combatant: The Deinosuchus has excelent base stats that allows it to be a good battle mount.
Damage Dealer: The Deinosuchus' Giga Bite does massive amount of damage per bite, allowing it to kill big creatures easily such as Rexes, Brontosaurus or even other Deinosuchus. (Level up Health and Damage)
Titan Killer: Its Giga Bite inflicts Bleeding to the target, allowing the easy kill of massive dangers such as the Titanosaur. (Level up Health and Damage)
Giga/Carcha Killer: The Deinosuchus is ignored by almost any hostile creature, this includes Giganotosaurus and Carcharodontosaurus, this in combination with its good base stats and massive damage output makes it excellent for hunting this apex predators and obtain Giganotosaurus Heart, or just to restart that importat spawn on the map. (Level up Health and Damage)
Boss Killer: Due to it's moderate drag weight and powerful bite. It is possible to bring a Deinosuchus into a boss arena and they can be used as a rather powerful mount. What lack in speed, they more then make up for in power. Plus, with the fractured debuff, you will be able to literally bleed down your enemies' health. (Level up Health and Damage)
PvP: Due to the fact that its Giga Bite applies Bleeding to the target, it can be used as a anti-soaker, specially underwater where it has better mobility. (Level up Health and Damage)
Tank: The Deinosuchus has a 50% damage reduction of any kind on its head, in addition to that all its body reduces the damage of many types of projectiles (See Abilities), both damage reductions in combination with its excellent base Health allows the Deinosuchus to tank many kinds of damage decently, including turrets. (Level up Health)
Ocean Explorer: The Deinosuchus is a very strong mount with good swimming speed, which means that this creature can deal with big dangers under the ocean such as Mosasaurus, Plesiosaurus or even Tusoteuthis. (Level up Health and Damage)
Explorer/Transport: The quick speed that the Deinosuchus has swimming and its good Weight stat allows its use for exploring or transporting heavy objects between two points. (Level up Stamina and Weight)
Tek Cave Fighter/Transport: The Deinosuchus is no detected by any hostile creature, this include Giganotosaurus and Carcharodontosaurus (Territorial creatures such as Therizinosaurus can still aggro the Deinosuchus if they are close to it), making it an excellent way to finish the Tek Cave even with a big army of Deinos without actually fighting on the Tek Cave to save health for the important fight. (Level up Health and Damage)
For information pertaining specifically to the real-world Deinosuchus, see the relevant Wikipedia article.
Deinosuchus sanguineus roughly translates to "bloodthirsty terrible crocodile."
The Deinosuchus has a skull that likely indicates a closer relation to alligators than crocodiles. The first detail that does so is its more U-shaped snout, as opposed to the crocodile's V-shaped snout. The second such detail is that when its mouth is closed, there are almost no lower teeth visible (although alligators do not have ANY lower teeth visible like this), instead of the crocodile's interlocking teeth.
