A civilization of intelligent dinosaurs emerged in the far future and developed time travel. They sent an agent back to the prehistoric era with a specific mission: retrieve intact eggs from five distinct dinosaur species, preserving genetic material that would otherwise vanish. The complication is timing. The asteroid that ended the Cretaceous epoch is twenty minutes away when the mission begins. Every second spent on extraction is a second closer to an impact that will not spare the agent regardless of their temporal origin.
