Though extremely heavy and cumbersome, it has likely evolved to protect against larger dinosaurs that live on the island. Unlike other mammoths, the steincaput has a separate tusk that grows upward out of the main tusk. Its name “stone head” is a reference to the bone “cap” formation on its skull. It is sometimes seen giving humans piggy-back rides, possibly because they think humans are ugly, hairless babies. The gigantopithecus on ARK is a fan of berries, but it probably strips entire bushes clean, leaves and all. It was an herbivore, eating so much bamboo that pandas look like they’re on a diet. Related to Gigantopithecus blacki, this ARK resident overshadows what was previously the largest ever existing ape, standing at almost ten feet tall. Abilities: Play with human, throw human, pull apart human.

Doedicurus doesn’t go looking for fights.

Because of its hard shell and club tail, other creatures on the island tend to leave them alone. Related to the modern armadillo and the extinct Doedicurus clavicaudatus, the custosaxum is built much rounder and sturdier than its cousins.

Appearance: Pleistocene and Halocene Epochs.

If there were ever gray wolves on ARK, it’s possible maxdirus ate them all. After much of its megafauna prey died during the Pleistocene extinction, dirus could not compete with its smaller, faster cousin, Canis lupus. Its cousin, Canis dirus, died out toward the end of the Pleistocene Epoch. Direwolf The Big Slobber Horse Mammalįound only on ARK, Maxdirus can be translated to “most fearsome dog.” Its already-apt name becomes more true when it hunts in a large, coordinated pack. It lacked the cochlea modern bats use to echolocate, so their diets may not have included many insects. Though the vicious specuncola is only found on the island known as “ARK,” Onychonycteris is the world’s oldest bat genus, existing over 52 million years ago. They never actually coexisted with dinosaurs on Earth, but it’s fun to see giant wolves battle against a carnotaur or hunt down a pachy.

Since dinosaurs usually get the royal treatment in video games, extinct mammals are a rare treat to see.
