Skeletal remains of various, mostly extinct species can be found in the game. The majority of these skeletons are found in the Lost River, aside from Reaper Leviathan skeletons which are found in the Inactive Lava Zone.
Some skeletons can be scanned, doing so will provide additional story information, or other information.
Skeletal Remains Found in Alien Habitat
This large creature was kept in the large aquarium of the Disease Research Facility for a long period of time for testing purposes. The skeleton is very odd in appearance, having a solid exterior shell, as well as an interior skeleton. The PDA notes shared skeletal traits with the Biter. It also states that this creature was a carnivorous life form.
The skeletal remains of a vast predator, discovered inside an artificial habitat at the alien research facility.
2. Cause of Death:
This huge skeleton is found outside the Lost River Laboratory and is surrounded by spotlights and cables. This species is presumed extinct. The skeleton is the only one known to exist and is approximately seven thousand years old. It appears to be some sort of huge carnivorous life form. The skeleton is composed of many bone plates. Running parallel on down either side of the skeleton are twelve large holes, the purpose of which is unknown. It has six eye sockets and many sharp teeth, each tooth being larger than the Player.
This skeleton is large enough that the player can swim through the gaps left by its missing teeth.
Projections suggest this lifeform would have been far larger than any living creature encountered on the planet. The remains date to seven thousand years ago.
Reaper Leviathan Skeletal Remains
Reaper Leviathan remains can be found on the floor of the Inactive Lava Zone. They are either found as whole skeletons, or just skulls. The Reapers came to be in the Inactive Lava Zone due to Sea Dragon Leviathans making infrequent trips to the surface to hunt them, and then bring them back down to eat.
Leviathan Skeletal Remains
This skeleton is found in the Lost River Junction. It belonged to a Sea Dragon Leviathan that attacked the Disease Research Facility in an attempt to retrieve its eggs that the Precursors had taken for testing purposes. The Sea Dragon's attack on the facility destroyed it, but also caused fatal head trauma to the Sea Dragon; it died not long after the attack. It is approximately one thousand years old.

1. Head Trauma:
This skeleton is ancient, approximately ten million years old and is found in the Lost River Bones Field. The skeleton belonged to an enormous super-predator, dwarfing both the Sea Dragon Leviathan and Sea Emperor. The remains consist of a huge, reptillian-esque skull and sixteen pairs of huge ribs. The skeleton is covered in flora and coral. The Precursors were also studying these remains, as evidenced by small, angular indentations on the ribcage. A smaller variant of this creature's skull can be found in the Ghost Forest.

- Aged to approximately ten million years old
NOTE: There are a series of precise, angular indentations on the rib cage, suggesting a third party has taken samples from the specimen at a previous time.
