Object Class Safe

Special Containment Procedures SCP is location-specific and unsuited for facility containment: it is therefore to be kept sealed and off limits to the civilian population. Initial signage designating the site as off-limits as a “sensitive archaeological site” attracted enquiries (site is in a valley frequented by hikers). Upon review, perimeter strength has been increased – site is now secured behind an electrified perimeter fence 100m from entrance and under video-surveillance - and signage altered to claim that the site is geologically stable and unsafe.

Two research assistants are to remain on-site and monitor activity: interested civilians will be informed that the research assistants are geologists. Both research assistants must be present on nights when SCP-2 is active, and at least one at all times – accommodation has been provided by the Foundation in on-site cabin adjacent to surveillance equipment.

Entrance to SCP itself (i.e. cave mouth) is sealed with a 15cm thick steel door affixed to the rockface. Door opens to combination of two keys, to be held individually by on-site research assistants. SCP is not to be accessed during instances of SCP-2 except for formal, pre-approved tests. Interior of SCP is continuously monitored by 6 CCTV cameras which feed to the on-site surveillance office and a remote surveillance office in Site 77.

SCP is currently classified as safe, but all instances of SCP-2 are to be assessed for potential to exceed current containment procedures, and any potential for such will be met with upgraded containment facilities. Research assistants are equipped with appropriate suppressant weaponry for potential breach situations.

Description SCP is a karst cave in the hills above the municipality of Kozina, Slovenia, near the Italian border. Entrance to the cave is an irregular circle with a diameter of c.2 metres: the cave extends into the hillside for c.320 metres while descending gradually: descent then becomes abrupt, essentially forming a vertical pit of depth c.10 metres: base of this pit is the limit of SCP.

This pit is filled almost to the “top”, i.e. the level of the cave floor before it deviates into the pit, with assorted animal bones (SCP-1). There are 2784 individual bones at last count, though some are fragmented and this figure has fluctuated since the discovery of SCP, owing to Foundation activity.
The bones belong to local species, chiefly mammals: there are no human bones present. Bones from species that formerly inhabited the area but have gone extinct within the last c.16,000 years are also present. The cave was formed by regular flood action, and one hypothesis suggests that the bones were deposited by water: another is that they were placed deliberately, though it is unclear who might have been responsible for this. The most recent bones were deposited sometime within the last 100 years.

Every 9th night, a number of the bones constituting SCP-1 self-assemble and self-animate into a single entity (referred to generally as SCP-2). Which bones these are and what assemblage they form varies unpredictably, but they always form a functioning skeleton: moreover, the assemblage subsequently behaves as though it were a living animal, moving as if it has musculature, appearing to exhibit sensory responses, etc. SCP-2 tends to move and act with a certain imperfection and awkwardness, but it has been suggested by numerous observers that this is not a physical limitation of the assemblage (which on occasion moves rapidly and confidently) but a “psychological” one, i.e. that because SCP-2 is newly constructed it is unsure of its own capabilities and physiology.

The assembly process takes, on average, 17 minutes and occurs spontaneously at sunset on the relevant night: the bones move without apparent outside force, assembling gradually into a “complete” skeleton. From the main passage of the cave, all that is evident is a certain disturbance of the bone pile, until eventually SCP-2 emerges, but cameras placed within the pile have captured the process, which always starts with a single bone and expands from there (although what bone this is is not consistent). The assembly is always performed seamlessly, as though to a pre-determined pattern.

SCP-2 behaves much as a “normal” wild animal might be expected to: it explores its surroundings as if new to them, interacts with others and is motionless and recumbent for long periods (generally interpreted as “sleep”). SCP-2 is usually timid, but on occasion appears hostile: this generally seems to correlate with the nature of the skeleton (for instance, a complete bear skeleton has attempted to attack researchers). If touched, SCP-2 feels like a skeleton, with no detectable evidence of musculature etc., despite the assemblage’s ability to move. SCP-2 is not capable of vocalisations, excretions etc.

Before SCP was enclosed, SCP-2 would apparently on occasion leave the cave: reports of a “haunted cave” led the foundation to make their initial investigation. Shortly before dawn, SCP-2 returns to SCP-1 and burrows into it before “collapsing”, disaggregating and returning to the bone pile.

In 73% of recorded instances of SCP-2 since observation commenced in X, SCP-2 has seemed to be the skeleton of a known species with at least some bones occurring in the bone pile. Most frequently, SCP-2 assembles as the skeleton of a cow (Bos taurus), one of three deer species (Cervus elaphus, Capreolus capreolus, Eucladoceros sp. [extinct]), a bear (Ursus arctos), a fox (Vulpes vulpes), a lynx (Felis sylvestris) or a horse (Equus ferus). However, these skeletons are generally not precise replicas of the genuine species, even where the materials are available (for instance, on X a “cow” skeleton was observed with several vertebrae belonging originally to a number of other species and a femur from a deer species of similar size and shape: this was in spite of the fact that there are sufficient bones in SCP-1 to compose a complete cow skeleton).

Numerous experiments involving the introduction of other bones to SCP-1 have been performed: see experiment logs below.

In the remaining 27% of instances, SCP-2 is anomalous: that is, it assembles as a species not currently recognised by science. These assemblages vary from fairly generic quadrupeds (i.e. too generic to be assigned a definite species) and plausible “variations” on existing species (for instance, on X, an apparent fox species with a tail longer than in any known fox species but not so long as to be evolutionarily unlikely assembled) to highly anomalous assemblages: some of these are detailed in the attached schedule below.

Extensive statistical analysis has not revealed any pattern to what species appears during any given instance of SCP-2. However, two distinct trends have been observed and confirmed after lengthy observation and tabulation. Firstly, anomalous instances of SCP-2 are increasingly common: the 27% figure for anomalous instances of SCP-2 is increasing by roughly .3% per year, and was approx. 19% when SCP was first discovered and enclosed. Of these anomalous SCP-2s, an increasing number deviate more extremely from known animals and indeed from plausible potential animals, although highly anomalous instances of SCP-2 are no less mobile and capable than others (and indeed often seem more so). The second trend is towards increasing use of bones in SCP-1 when assembling SCP-2. Most SCP-2 assemblages involve 100-200 bones, in common with extant animal skeletons. Highly anomalous instances of SCP-2 tend increasingly to include more bones and to be correspondingly larger: the average number of bones used in such highly anomalous assemblages is estimated at 400-500. Some researchers have begun to speculate about the possible composition and anatomy of an instance of SCP-2 that would consist of most or all the bones in SCP-1. This hypothetical entity would be [DATA EXPUNGED].

Addendum 1 – Test Logs

Test A – Date X
Procedure: Several spotted hyena (Crocuta crocuta) skeletons were added to SCP-1 to ascertain whether bones artificially introduced and belonging to non-native animals would be subject to SCP.
Result: Introduced bones wee observed being incorporated into SCP-2 assemblages, and one instance of SCP-2 assembling as a hyena was observed. Hyena bones were subsequently removed to prevent potential contamination of SCP.

Test B – Date X
Procedure: All of SCP-1 was temporarily removed from SCP and replaced with a random assortment of native animal bones of approximately the same total volume as SCP-1.
Result: Bones assembled into SCP-2 as per bones of SCP-1, suggesting that SCP-2 assembly is a property of SCP rather than of SCP-1. Original SCP-1 bones were subsequently returned, and introduced bones removed.

Test C – Date X
Procedure: Concurrently with Test B, the removed SCP-1 was monitored for signs of assemblage while outside SCP.
Result: No assemblage occurred, which tends to support the implications of Test B.

Test D – Date X
Procedure: Human bones were introduced to SCP-1.
Result: After 7 assemblages, no human bones had been incorporated into any instance of SCP-2. Test discontinued in favour of Test E.

Test E – Date X
Procedure: Usual SCP-1 bone pile was entirely removed, replaced with seven disassembled human skeletons.
Result: No assembly of SCP-2 occurred. SCP appears not to affect human bones.

Test F – Date X
Procedure: Following Test E and before reintroduction of SCP-1, seven disassembled chimpanzee (Pan troglodytes) skeletons were introduced.
Result: Assembly of SCP-2 (as a chimpanzee skeleton) occurred. Nine nights later, assembly into an anomalous SCP-2 (chimpanzee skeleton with six arms) occurred. SCP affects other extant primates.

Test G – Date X
Procedure: Following Test F and before reintroduction of SCP-1, seven disassembled skeletons of Homo habilis (from the Foundation's stores) were introduced.
Result: No assembly occurred. SCP appears not to affect early humans.

Test H – Date X
Procedure: SCP-1 was returned to SCP, along with a large number of replica bones of various kinds (plaster, resin etc.)
Result: SCP-2 assembles as normal several times without incorporating any of the replica bones. Replica bones removed.

Test I – Date X
Procedure: SCP-1 removed and replaced with 10 kilos of desiccated arthropod exoskeletons.
Result: No assembly occurred.

Test J – Date X
Procedure: All but one bone (femur of Lynx lynx) removed.
Result: SCP-2 did not assemble.

Test K – Date X
Procedure: Further bones from Lynx lynx were added in single increments on each night on which SCP-2 would ordinarily assemble.
Result: SCP-2 did not assemble for the next 7 nights when an assembly would normally be observed. Once the ninth bone was added, an extremely simple instance of SCP-2 assembled but appeared to be almost unviable, capable only of small, undirected motions (SCP-2 in this instance resembled a haphazard chain of bones). Bones continued to be added in single increments, and resulting instances of SCP-2 became increasingly “complete” and “sophisticated.” Entirety of SCP-1 (barring 3 bones removed for ultimately inconclusive testing) was then returned and testing schedule suspended pending new test concepts.

Anybody got any skeletal SCPs or whathaveyou they wanna put in this thing? Could be interesting. - Dr X

Test L – Date X
Procedure: A shipping contained was placed outside the door to SCP, with the door open, a few hours before an instance of SCP-2 was due to assemble. On this occasion, SCP-2 assembled as an instance of Bos taurus. As hoped, it wandered through the open door into the shipping container, at which point the door was closed behind it.
Result: As dawn approached, SCP-2 became increasingly frantic and began to butt and kick the closed door leading back to SCP-1. At the point in time at which SCP-2 ordinarily disaggregates into SCP-1, SCP-2 did not disaggregate, and continued to show signs of wanting to return to SCP-1. After a further 48 hours, during which SCP-2 became increasingly aggressive, to the point of fracturing several of its constituent bones against the door of SCP, the door was opened on the orders of Dr X. SCP-2 moved as fast as it was able towards SCP-1 but, upon arrival, did not disaggregate, and to date has not done so. Recaptured and designated SCP-2a, it is now kept in a secure chamber in the Safe wing of Site 77. It appears to have largely “accepted” its inability to return to SCP-1 and is now largely passive, not requiring any form of sustenance. Further tests of this kind have yet to be approved.

Addendum 2 – Selected Highly Anomalous Instances of SCP-2

Date X
SCP-2 appeared to be assembling as a bear, but included several pairs of antlers across its spinal ridge. Exhibited unusually aggressive behaviour (ramming the door, scraping antlers along the walls, gnawing rocky outcrops).

Date X
SCP-2 assembled as a horse. Assemblage also included four additional legs, assembled from horse, deer and cow bones. SCP-2 was restless for entire night, evidently wanted larger space in which to exercise.

Date X
SCP-2 assembled around a bear skull but departed radically from usual skeletal forms, constructing a cephalod-like array of “limbs” made largely of chains of vertebrae fanning out from the base of the skull. Assemblage proved able to move on all surfaces of the cave with equal ease.

Date X
SCP-2 assembled into a complex, articulated form with six limbs, four used for locomotion and two – with long, slender fingers composed largely of fox limb bones – for grasping. Was largely dormant for the night.

Date X
SCP-2 assembled into upright creature using an elaborate system of cantilevered ribs and pelvic bones: demonstrated ability to sprint on two hind limbs while holding horse skull erect.

Date X
SCP-2 spent over half an hour assembling into sizeable, vaguely crocodile-like creature (roughly 3x the size of a Nile crocodile) with horse's skull, large, wide-set legs and hefty tail.
Jesus, it looks like it's trying to be 682. - Dr X

Date X
SCP assembled into basic quadruped with complex array of bones emerging from shoulderblades. Array had the appearance of wings, but seemed to be non-functional.

Date X
SCP-2 assembled into snake-like chain of bones as long as SCP. No visible head, but exhibited sensory responses. Spent the night writhing in a continuous circuit through the cave.

Anyone else feel like this thing is – to put it unscientifically – the world's most fucked-up Lego set, and someone's lost the instructions and keeps trying to remember what it's supposed to make? - Dr X
