 SCP-250 is the animate fossil skeleton of an allosaur. However, an incomplete scientific article found in the personal effects of paleontologist Dr. Pruitt 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. Many of this force is hindered by SCP-250's aggressive behavior, which has been assessed by Foundation paleozoologists 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.
