Lystrosaurus Amicifidelis is a small herbivore, common to much of the island. Only about two feet long, it is not high on the food chain, and eats small plant life. The poisonous insects of the island seem to have little effect on Lystrosaurus.

Despite being one of the Island's tinier herbivores, Lystrosaurus is an incredibly resilient survivor. It recovers its torpor and health much faster than most creatures, which makes rendering a Lystrosaurus a rather difficult affair.


Not surprisingly, Lystrosaurus is an extremely loyal pet once tamed. It's a very fast learner, so it gains experience much faster than most other creatures. Additionally, its presence nearby appears to inspire allies, making them learn and gain experience more rapidly as well. Thusly, Lystrosaurus is an excellent addition to any tribe's hunting party.

— The Dossier

The Lystrosaurus is a small herbivorous mammal (synapsid) found on the Ark.

Wikipedia has a more detailed and comprehensive article on Lystrosaurus


The Lystrosaurus is a stout mammal-like reptile often described as resembling a reptilian pig. Like wild pigs, they are usually seen snuffling the jungle floor for food using two small canine teeth and a small but strong beak. The Lystrosaurus's only true defense is their stealth, being small and quiet makes them incredibly difficult to find.


The Lystrosaurus is passive.
