Found in small numbers within the Island's colder regions, Chalicotherium Obsideoquus is normally a peaceful herbivore that prefers to spend its days lazing about or playing with it's family. It is very territorial, however, and the entire family, young and old, will turn against an encroaching creature at just the slightest provocation.

A strange scene to stumble upon is a group of Chalicotherium playing. One odd playtime activity for Chalicotherium is hurling large balls of snow or mud-rocks at each other. Smaller creatures in the area shy away from Chalicotherium during this exertion, for fear of being buried in snow or gravel.


While many creatures are useful while attacking a fortress, Chalicotherium can be trained as mobile artillery. Its unique playtime habit becomes a rather devastating long-range assault tactic when it is given boulders to throw, rather than snowballs!

— The Dossier

The Chalicotherium is a large herbivorous mammal found on the Ark.

Wikipedia has a more detailed and comprehensive article on Chalicotherium





Perhaps the oddest mammal on the island, the Chalicotherium is best described as a hybrid between a horse, a gorilla, and a panda. Like a gorilla it walks on its knuckles, but whereas apes have hands, the Chalicotherium bears wicked claws. These claws are used for pulling leafy branches towards its mouth, but are deadly in combat. The creature seems to bear some rudimentary intelligence not unlike an otter as troops of them can be seen hurling snowballs at each other like some sort of war game - something that also proves handy against local predators like Hyaenodons and Direwolves.

Color Scheme and Regions






The Chalicotherium is unable to be tamed through the standard tranquilize-and-feed methods, and must be tamed non-violently.

To feed it, place Beer Jars on the last slot of your hotbar, then when approached press use (default E) to feed it. You cannot feed them all the food required for taming at one time, you must wait every couple of minutes until it is hungry again to feed it more until its taming meter is filled.
