The Brontosaurus (bron-tuh-SAWR-uhs) is a species of dinosaur in ARK: Survival Evolved, and is one of the largest creatures in the game.

Basic Info[edit | edit source]

Dossier[edit | edit source]

This dossier section is intended to be an exact copy of what the survivor Helena, the author of the dossiers has written. There may be some discrepancies between this text and the in-game creatures.


Among giant creatures I've seen on the Island, Brontosaurus lazarus is larger than any sauropod I've read about. In fact, the dinosaur is so massive that it serenely ignores most other creatures.

I've seen a pack of raptors tear apart small dinosaurs while Brontosaurus continues eating, seemingly oblivious to the hunting pack.


Because of how docile it is, the Brontosaurus makes for an ideal pack animal. Peaceful tribes use it to carry incredible quantities of resources, while warring tribes use it to mobilize their army. Its size and strength make it one of the unique creatures on the Island that can support a "platform" saddle. Unfortunately, its enormity means that the process of taming a Brontosaurus can take a very long time.

Some may think this is an Apatosaurus, Dreadnoughtus, Argentinosaurus, or some other sauropod, but this is a strange Island, and I'm the one doing the research. I'm convinced that this genus is Brontosaurus, and no one can tell me otherwise. My study, my rules.

~ Helena

Behavior[edit | edit source]

Brontosaurus is not aggressive, but can deal damage to players or dinosaurs by stepping on them if provoked. Another attack that they do is a tail swipe, which, for low to mid-level characters, can be a 1 or 2 hit death. The tail swipe does more damage than the stomping, has a long reach, and will fling you in the direction the swipe traveled. The Brontosaurus also has a large amount of health. If you want to kill one, ranged weapons or high-level hunting dinos are recommended.

Appearance[edit | edit source]

The Brontosaurus is a gigantic sauropod dinosaur, unmistakable for any other species in both size and appearance. It is usually found alone or in small groups, browsing at heights well above that of smaller herbivores or along beaches. Its size and strength make it almost impervious to predation... save perhaps for audacious tribes.

Color Scheme and Regions

This section displays the Brontosaurus's natural colors and regions. For demonstration, the regions below are colored red over an albino Brontosaurus. The colored squares shown underneath each region's description are the colors that the Brontosaurus 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 Brontosaurus's "body" magenta.

Drops[edit | edit source]

Guaranteed Special Loot

To get the Sauropod Vertebra you must access the dead dinosaur's inventory.

Because of the Brontosaurus' sheer size, they drop large quantities of Raw Meat and Raw Prime Meat. Because of this, killing a Brontosaurus is ideal for a carnivorous effective tame, such as a Rex. That is, before it spoils due to its fast spoil timer. Recommended to kill a Brontosaurus close to your tame so the prime meat doesn't spoil.

Base Stats and Growth[edit | edit source]

Note that creatures will have different stats in Survival of the Fittest

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.

Taming[edit | edit source]

For general infos about domesticating a wild creature see Taming.

KO Strategy[edit | edit source]

  • The best method would be using a Scorpion, Tranquilizer Arrows, or Tranquilizer Darts, but if those are not available to you, then a simple Slingshot will do the trick (100+ stone).
  • Attacking a Brontosaurus from the top of a tall, steep cliff can allow you to attack it while staying out of range of its powerful attacks.
  • Lay down a wood or stone foundation with 3 wood or stone walls and wooden one door. Above the first layer place 4 wooden frames with no doors. Stand inside your shelter and shoot it. It won't damage you just your shelter.
  • Get a friend to pick you up with a flyer and fly you over the bronto. From there you just need to shoot it. Just make sure that you and your friend are high enough so the bronto can't hit you!
  • You can shoot the bronto while riding another land mount and kite it to a safer location for taming.
  • You can outrun the Brontosaurus backwards. just walk backwards facing the Brontosaurus. After that shoot it with your Tranquilizer Arrows.

Combat[edit | edit source]

This section describes how to fight against the Brontosaurus.

General[edit | edit source]

The Brontosaurus has the second highest health pool of any herbivore behind the Titanosaur and it has the base damage of a Rex. Their attack has a massive range and huge knockback which makes this creature dangerous when riled up. Avoid, unless it is necessary to attack. Also, try to avoid attacking small creatures such as Dilophosaurus, near a Brontosaurus, as you could accidentally hit the Bronto, and aggro it.

Strategy[edit | edit source]

If on foot, try to keep distance. Their tail-sweeping attack has a massive range and can knock a player or attacking animal off slopes or cliffs. They can be stuck behind rocks and cliffs and shot at safely. A strong mount can defeat the Bronto with dedicated attacking, but your mount must be able to withstand a high amount of damage. Large carnivores like a Rex, Spino or Giganotosaurus can kill a Bronto with ease, provided the player does not make a mistake during the battle.

It is extremely easy to kill a wild Bronto even at lower levels by getting its attention and then sailing out into deep waters far from land with it following you. While sitting in the pilot's seat of a raft, it won't acknowledge your presence, and thus you may drown it by simply getting it further away from shore than it can swim back, and it will sink until it dies.

Weaponry[edit | edit source]

Attacking with melee on foot is never a good idea, as the Brontosaurus has massive damage and knockback making it difficult to even reach it. Using a ranged weapon or a strong dino is recommended. A ballista on a raft can also be effective as long as you have enough bolts.

Dangers[edit | edit source]

Their tail swing will throw attackers back, potentially off ledges and cliffs. If the attacker is not fast enough to recover the distance before it swings again, the Bronto can easily hold them back. A Bronto's legs also inflict damage(crushing damage) in huge amounts very quickly versus players, so it is recommended that players do not get caught underfoot or they will likely be trampled to death.

Weakness[edit | edit source]

Despite its massive range, the Brontosaurus is very slow in terms of movement and attack rate. Their massive size allows them to be stuck behind cliffs and large boulders much easier than others. They also will attempt to retreat when wounded, where it won't fight back but can still deal damage if players are under it. It should also be noted that, from the front, their tail hits either to the left or right and can be dodged by strafing the opposite direction quickly. Using this technique it is easily possible to slay a Bronto without taking any damage on foot with a bow or crossbow.

The Bronto will also have trouble hitting you if you attack its back with a flying mount such as the Argentavis. If you have a flying mount to attack with, it is best to swoop and hit the backside of its head.

If you are riding a Bronto, it is problematic to have another Bronto following you. Even at maximum following distance, the elongated neck will regularly clip into you, requiring you to dismount and have the dinos follow you for a bit.

Utility[edit | edit source]

Roles[edit | edit source]

  • Tank: Decent tank due to its high HP (Level up Health.png Health and Melee Damage.png Melee Damage).
  • Damage: Very good AOE and base damage. Too slow to chase down prey (Level up Melee Damage.png Melee Damage, Stamina.png Stamina and some Movement Speed.png Movement Speed).
  • Transport: While slow, it has the third best base carrying capacity in-game. Good for local transport (Level up Weight.png Weight, Movement Speed.png Movement Speed and Stamina.png Stamina).
  • Gatherer: Excellent for gathering materials. If you tell the Bronto to attack near plants, you will acquire an enormous amount of resources (Level up Melee Damage.png Melee Damage and Stamina.png Stamina).
  • Mobile Base Platform: Use a Platform Saddle to build a mobile base on the back of your Brontosaurus. Structures do not affect Dinosaur weight capacity, but storage does; increase weight if used for transport (Level up Health.png Health, Movement Speed.png Movement Speed and Stamina.png Stamina).
  • Wall Defender: Very effective in PVP, placing your Bronto by your outer walls can be a fantastic strategy to keep away players. Weigh down the bronto and keep it by the walls so that it is in the exact place you want it. Level up Health.png Health, Melee Damage.png Melee Damage

Notes/Trivia[edit | edit source]

For information pertaining specifically to the real-world Brontosaurus, see the relevant Wikipedia article

  • The full name roughly means "God-helped thunder lizard".
  • Brontosaurus are one of the endgame berry farming machines you will wish to have. Use their attacks against large groups of bushes to gather more than a hundred berries. Depending on your location, you'll be able to farm more than 1500 Narcoberries in one, single ingame night. Also, due to their enormous weight capacity, they make transport of large quantities slow, but effective.
  • Brontosaurus' tail attack is extremely wide, and reaches almost up to its head in a 180° whip in the direction you are facing. Caution is advised when using tail attacks to collect berries, because you might hit a herd of Trike.png Triceratops, causing all of them to attack you, which can be overwhelming for even the Bronto.
  • The dossier mistakenly places Brontosaurus' time period as the late Cretaceous when, in fact, it actually lived in the late Jurassic. However, the dossier also acknowledges that it may be another sauropod like Argentinosaurus, which did come from the late Cretaceous.
  • The Brontosaurus is so large that when it steps on smaller creatures (such as trilobites, meganeuras, or dodos) it deals damage to them and sometimes even kills them. This can be a problem, especially when navigating through swamps, as you frequently step on Meganeura.png Meganeuras, killing them and causing a couple of them to attack you at a time. One tail sweep often kills all of them, earning you a lot of experience points.
  • The skull of the animal shown in the dossier is not of the real-life Brontosaurus, which to this date has yet to be found, but Camarasaurus. This appears to be a reference to the previously common use of Camarasaurus skull casts for sculpted models of Brontosaurus skulls, before it become widely accepted that Brontosaurus most likely had a Diplodocus-like skull.
