Scp-XXXX has been confirmed in recent study, to have arrived from the cosmos. space debris and other worldly elements recently found on site indicate that scp-XXXX arrived inside a meteor. Again, we have know idea how long ago this occurred, but it could have caused the Triassic-Jurassic extinction through this event. Or… more terrifying still, it could have caused earth's first extinction, and scp-XXXX is responsible for all other extinctions to come.
