What are those giant animals on Genna that Dek and Bud chase down in the Razor Grass field in Predator: Badlands? Those massive four-legged creatures with the elephant trunk-like proboscis are officially called Bone Bison. This article details everything we know about this giant creature and what its role is on the planet of Genna.
Bone Bison are Kalisk food
While the Bone Bison might look intimidating and aggressive, they're actually a prey animal native to Genna. Thia remarks that they are food for the Kalisk – which explains why Bud was discovered at this juncture as well and why she was hunting down the creatures too.

Design and Traits
The Bone Bison got its name due to its rigid exoskeleton-like plates which cover strategic parts of its body. Its hide is completely covered in dense bone, making it nearly impenetrable. Its head features a massive axe-shaped bone structure which protects the Bone Bison's extremely soft and vulnerable inner flesh. Acting like laterally-hinged jaws, the axe-like mouth opens up to reveal a trunk-like proboscis which the Bone Bison uses to eat. Exposing this proboscis is also a weakness however, which Dek exploits in the film – a simple throw of his Lazer Sword is enough to completely slice through the Bone Bison's entire body with ease.

The Bone Bison grazes in the Razor Grass fields to avoid predators, since the Razor Grass make traversing the landscape nearly impossible for most other lifeforms on Genna. The Kalisk and the Bone Bison are the only two creatures on the planet specifically adapted to move through Razor Grass without getting sliced to bits.
Bone Bison meat is apparently not sweet and Yautja are able to eat and metabolize its tissue.
