A new find of an isolated prosoma of the possible aglaspidid arthropod Zonozoe drabowiensis from the Řevnice Quartzite of the Libeň Formation is described. All previously described specimens from the Letná Formation were measured and compared to this specimen, which shows the so far unknown external surface of the exoskeleton and represents the first occurrence outside the Letná Formation.
