Doedicurus Custosaxum is one of the island’s non-aggressive herbivores, generally found on mountains and grasslands. Large and well-armored, it has a supply of fat under its plates to keep it warm and fed in the cold.
Doedicurus has adapted well to the dangers of the island, perhaps even better than the Ankylosaurus.
Doedicurus has two very different reactions to predators. Against smaller foes, it generally uses its spiked tail to inflict as much damage as possible. Against larger predators, however, it pulls its tail underneath itself to form a solid armored ball that is nearly impossible for creatures to pierce.
Doedicurus is a highly prized work animal on the island. Its spiked tail is ideal for quickly swattering the large rocks, so Doedicurus is a very efficient quarry worker. And in case their quarry gets raided, Doedicurus-Riders have a very difficult-to-kill mount!
— The Dossier
The Doedicurus is a medium sized herbivorous mammal found on the Ark.
Doedicurus can be tamed like most other herbivores, utilizing Narcoberries/Narcotics and Mejoberries or Kibble. However it has been noted that they may prefer Rockarrot or Citronal. Doedicurus can be ridden, with the saddle being unlocked at level 35 and is crafted in the Smithy.
- Doedicurus can roll up into a ball and roll around, even with a rider on its back. It is the only animal in Ark that can do this.
- The full name of the Doedicurus custosaxum translates to "Pestle-tailed stone warden", likely a reference to its use in gathering stone and defensive capabilities.
- Unlike the Ankylosaurus, the Doedicurus can not use its melee attack while being carried by a Quetzalcoatlus.
- A Doedicurus with Wandering Disabled parked at the front of a raft can gather incredible amounts of stone for the player when sailed up a rock-choked river. The creature will swing at rocks as they pass and his burden becomes irrelevant. This handily compensates for the inability to bypass his burden with a Quetzal as detailed above.
- Any Doedicurus that has rolled into a defensive ball will not uncurl if it finds itself under water and will swiftly drown. Players with access to a Quetzal will likely find this the quickest method of killing unwanted low level spawns.
- Blue Doedicurus can rarely spawn in the wild. This, together with their ability to roll into a ball and charge their enemies, is possibly a reference to the video game character Sonic the Hedgehog, a blue hedgehog whose signature attack is to roll into a ball to charge at enemies.
- Doedicurus can still be knocked out when curled up.
Trivia not relevant for the game
- Doedicurus belongs to a group of armadillo-like (They are, indeed, related) mammals known as Glyptodonts.
