 Item number SCP-250 Object Class Euclid Special Containment Procedures SCP-250 is to be kept in a 50 meter by 50 meter enclosure simulating a prairie environment, with padded steel walls 15 meters high and 1 meter thick. The temperature must remain between 20 and 28 degrees Celsius by day, and between 10 and 14 degrees Celsius by night, with an average humidity of no more than 8%. This serves the dual purpose of ensuring that SCP-250's overall behavior remains predictable and of maintaining the physical integrity of its component parts. Vegetation within the enclosure is to be maintained on a weekly basis. See Document 250-MB-48 for details. Although SCP-250 does not physically require nutrition, it is to be fed one live adult pig every two days in order to regulate its aggression and hunting instincts. The remnants of its meal are to be removed from its enclosure no less than one hour after the onset of its nightly dormancy period. This includes cleaning any residual biological debris from SCP-250's physical components with compressed air and whisk brooms. At no point during cleaning are any of SCP-250's physical components to be moved by more than 1 meter in any direction, as this risk disrupting its dormancy. SCP-250 ends within 5 minutes of sunrise. Access to SCP-250's containment during its activity period is prohibited. Description SCP-250 is the animate fossil skeleton of an allosaur, originally identified as Allosaurus fragilis. However, an incomplete scientific article found the personal effects of paleontologist Dr. ██████ indicates that this classification may have been erroneous. It consists of 153 disarticulated bones and 14 plaster and fiberglass replacements held together and animated by an unknown force. Study of this force is hindered by SCP-250's aggressive behavior, which had been assessed by a Foundation paleontologist as being well within theoretical norms for an Allosaurus. SCP-250 emulates what are presumed to have been the standard daily activities of a living Allosaurus. It wonders its enclosure by day, enters a state of dormancy by night, and will attempt to kill and devour anything which it perceives as suitable prey, including humans. Its lack of organs does not seem to affect its behavior in any way, except that the remains of any prey it consumes will inevitably fall out of the gaps in its skull, neck and rib cage, at which point it ignores them. SCP-250 was first excavated as an 80% skeleton in ██████, 19███. Departments from the excavation did not include any reports of anomalies. In 19██, it was transferred to the ████ Museum of ████-N, where it was assembled, mounted and put on display. On the night of ██, 2000, SCP-250 seized and killed an intruder to the museum. Although damage to the intruder remains from so extensive as to render forensic identification impractical, they were conclusively shown to not be those of paleontologist Dr ████, whose office in the museum was extensively vandalized at night and who has not been seen since. Foundation personnel embedded within the museum staff reported the incident, and SCP-250 was taken into custody.
