Jurassic Jungle
Journey to the Jurassic Jungle and discover the blocks that time forgot! Whether you’re climbing the Primal Preserve’s towering trees or slogging through the Saurian Swamp’s ancient mud, you’d better watch your back: the locals are big, hungry, and more than happy to make you extinct.

The Jurassic Jungle (also known to be called Primal Preserve and Saurian Swamp) is a Prime World biome filled with a Dinosaur infested Jungle. It exists in any Adventure Worlds leveled Uber 4 or higher and can appear in either small patches or massive chunks of land. Meteorite Fragments can only be obtained here.

Jurassic Jungle icon as seen on the mini-map

Jurassic Jungle biomes are displayed on the map as forest green areas with dino prints. The biome has a chance to spawn two different variants, the Primal Preserve (Forest Canopy) and the Saurian Swamp. The Primal Preserve consists of two different layers of the world, the Canopy (Upper Layer) and Deep Forest (Ground Level) each with a different set of mob spawns and lair/dungeon spawns. The Canopy area is the only location that spawns Meteorites that drop Meteorite Fragments. The Swamplands consists of multiple riverbanks and lakes. This biome also spawns different mobs in comparison to the Primal Preserve.

Different mobs will spawn depending their location. Enemies that roam this biome include dinosaurs such as Archeosaurus, Therizinosaurus and Triceratops and occasionally tribal inhabitants such as apes, birds and frogs. The Tyrannosaurus Rex has a chance to spawn rarely in this biome and will always have a Buff and a large amount of health, making it a formidable opponent.

This is the home of the Dino Tamer.
