Interior view of SCP-XXXX, taken by Z5's camera before the discovery of SCP-XXXX-1.

Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedure:
SCP-XXXX is currently contained in Site-56, which is currently set up under the guise of a petroleum processing company. No personnel without at least level 2 clearance are to allowed access to Site-56.

Any instances of SCP-XXXX-3 seen crawling out of SCP-XXXX are to be pushed back into SCP-XXXX, termination is authorized as a last resort action. A live cow is to be fed to SCP-XXXX once every 2 weeks to ensure that SCP-XXXX's fauna doesn't die out.


SCP-XXXX is a chasm located in a remote area of Scotland, the length and depth of SCP-XXXX are unknown. SCP-XXXX was brought to attention after a report about the carbon dating from the surface around SCP-XXXX and from its interior is inconsistent with the surrounding area. The oxygen level inside and around SCP-XXXX is at the same atmospheric level of 35% as in the Carboniferous. It is unknown how SCP-XXXX is capable of restraining the air pressure and oxygen level inside itself.

SCP-XXXX's interior is very dark and small, the flora inside SCP-XXXX is minimal due to the lack of sunlight coming through. SCP-XXXX's fauna contains a group of various insects, all of these instances are labelled SCP-XXXX-1 to SCP-XXXX-6. It is unknown how the colonies managed to survive from the Carboniferous era to the present, researchers have theorized that the colonies underwent an hibernating state for several years and managed to stay alive. The most notable and common species includes:

SCP-XXXX-1: A Weta species ressembling Deinacrida heteracantha, brown and yellow in color, they are pack-hunting predators. Growing up to a meter long, SCP-XXXX-1 use their overwhelming number to swarm a prey in huge numbers.

SCP-XXXX-2: Arthropods confirmed to be Arthropleura armata.

SCP-XXXX-3: A spiderlike hexapod. SCP-XXXX-3 use their natural black color to blend in with the dark walls of SCP-XXXX. SCP-XXXX-3 are large 1 to 2 meter tall predatory insects that dwell at the bottom of SCP-XXXX. Being scavengers, they tend to lurk on the edges of SCP-XXXX trying to catch and feed on anything coming near their pincers. The SCP-XXXX-3 instances are the most common species seen trying to crawl out of SCP-XXXX.

SCP-XXXX-4: An unidentified worm species, SCP-XXXX-4 are massive, predatory flatworms, lacking eyes or a face of any sort. SCP-XXXX-4 measure 2 to 4 meters long. SCP-XXXX-4 are scavengers feeding on anything that they can catch. SCP-XXXX-4 are slow-moving but relentless, they surround their prey and tear it apart by grabbing the limbs and tearing them off. Instances of SCP-XXXX-4 have a symbiotic relationship with SCP-XXXX-3, the SCP-XXXX-3 colonies use the SCP-XXXX-4 has hosts for their young, similar to Pompilidae pepsis (Tarantula Hawk).

SCP-XXXX-5: A Solifugae species (later named Galeodes grandipotens). SCP-XXXX-5 are dark-colored galeodid sun spider measuring 15 to 20 centimeters. SCP-XXXX-5 sport huge crushing mandibles and posseses paralytic venom capable of causing significant pain to an human adult and paralysis to smaller animals.

SCP-XXXX-6: A cricket-like creature 1.5 to 3 meter in length depending of the individuals, SCP-XXXX-6 have an heavily-plated exoskeleton, four crawling legs, and two bladed forearms used to tear apart preys, their overall coloration is greenish-brown.
