Tables: Nauplius larva in chert

TABLE 1. Measurements for all specimens in micrometers with reference to appearance on certain figures. Brackets indicate uncertainties in assignment to certain size class or in measured values due to weak preservation. Specimen AUGD 12445C is mentioned, as it was documented and received a number, but later turned out as not being part of a crustacean. Numbers in first row mean: 1 = Figure; 2 = Repository number AUGD; 3 = Size class; 4 = Diameter of mandibular exopod (d1); 5 = Diameter of antennal exopod (d2); 6 = Diameter of exopod with unclear affinities; 7 = Diameter of antennal endopod (d3); 8 = Diameter of mandibular endopod; 9 = Height of antennal coxa in proximal-distal axis (h); 10 = Length of antennal coxa in median-lateral axis (l).
