SCP-250, or "Most of an Allosaurus", is an upcoming SCP in SCP: Unity that will be added in an as of yet unannounced update.
SCP-250 is the animate fossil skeleton of an allosaur. 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 has been assessed by Foundation palaeozoologists 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 wanders 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 in that the remains of any prey it consumes will inevitably fall out of the gaps in its skull, neck, and ribcage, at which point it ignores them.
SCP-250 is not currently in-game.
