Josephoartigasia monesi: The Center's giant deep sea diving capyabara!



The Josephoartigasia was the largest rodent to ever exist, approaching near the size of an american bison. Living in South America from 3 to 2 million years ago, it was a neighbor to other iconic south american megafauna like giant ground sloths, glyptodonts, and terror birds. Living on an island continent, it filled the ecological niche that hippos fill today, that of large, amphibious herbivores. Given this, and the geography of the Center, I believe it would be right at home on the map. A useful, amphibious tame full of abilities, this giant rodent can take you across the map's landscape, travel across the waterways, and even fulfill your deep sea diving adventures.

-Standard bite: A standard bite that can deal damage and collect materials 


-Pacify: Modern capybaras are renowned for their ability to get along with seemingly all types of creatures, and on an Ark full of predators the Josephoartigasia has taken this a step further. Like their modern relatives, their fur is oily. This oil in their dense fur secretes a serum that pacifies the creatures around it. Once tamed this oil can be passively collected and refined into a new form of darts, which, opposite to the ammonite bile darts that anger every creature around them, pacifies all creatures around them. This, in the right hands, can be very beneficial for taming as it’ll make your target docile for a short period of time. This oil can also be used the same way normal oil can, and can be rubbed off onto a survivor giving them a temporary passive effect for as long as the oil stays on.


-Water buff: Similar to the spino and shadowmane, while making contact with water it will receive a buff that gives it added speed and damage.


-Chomp and knaw: Rodents have some of the most durable teeth in nature, and the biggest rodent is no different. Able to knaw and chomp on structures they can wear down and break all structures below metal and tek.


Behavior: Josephoartigasia are generally passive creatures, and can be approached safely by survivors. While not completely tied to the water, they are most comfortable around it. When attacked, they will fight back, but once their health has been lowered enough they’ll attempt to pacify before running back to the water. They can actually run fairly fast, meaning that they can get back to the water quickly. While they spend most of the day in the water with regular but quick trips to the shore to forage, they spend most of the night grazing on land. This makes taming at night easier since they are more readily available to begin the process. During the day while in the water they are often seen submerged with their heads, nose and ears sticking out of the water, similar to a hippo(see reference below).

Taming: Tamed passively, these large animals mainly subsist on aquatic foliage, however they like to knaw and maintain the condition of their teeth every now and then. Survivors can tame them by placing structures near them, then wait for them to approach. Once next to a structure, the Josephoartigasia will gnaw on said structure. This preoccupies them, allowing for a survivor to approach them and feed them their preferred food, honey and superior kibble. Note that wooden structures seem to be best suited for this, with wooden foundations paired with walls and door frames being most suitable.


Saddle: There are two options when it comes to saddles. A basic saddle that can be unlocked earlier, and a submarine type saddle that can be used as a small mobile water port. Similar to the andrewsarchus turret saddle but for the water, this small submarine type saddle comes equipped with a light that can make swimming through the map's abyss easier. When inside their advisable air, meaning no matter how deep you go you won’t have to worry about running out of air while inside. The submarine is small, proportionate to a small platform saddle, but is still large enough to have a harpoon launcher and jets for added speed attached to its sides. This saddle can hold two passengers, while the normal saddle can only hold one.

Appearance: While resembling the real animal, it has color patterns similar to its closest living relative, the Pacarana(see reference down below). Its appearance and color pattern will also greatly resemble a capybara but with a broader build and longer tail. About the size of a trike, they are sizable creatures and much bigger than Ark's other amphibious rodent, the castoroides.North American pacarana (SciiFii) | Novum Terram Wiki | Fandom

So cool!

Hope someone makes this into a mod, i could totally see It being in ark additions.

Thank you! Even tho I'm gonna bring this submission back for the Valguero vote I'd still definitely love seeing it in mod form. Knowing how high quality Ark Additions is they could definitely do this idea and creature justice. Plus since mods are coming to consoles with Ascended it would mean that everyone could enjoy it, which would be great.
