Ancient Skeleton

This skeleton belonging to a Leviathan Class Organism is found outside the Lost River Laboratory Cache surrounded by scanners and cables. This species is presumed extinct. The skeleton is the only one known to exist and is approximately one million 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.

Trivia

 * The Ancient Skeleton was once named Ancient Skull. It was named this up until a livestream in which it was pointed out to narrative designer Tom Jubert that the incorrectly designated "skull" had a spine and ribs within it, so was clearly not just a skull, but also the body.
