(1) Within 48 hours, we washed the samples, removing inorganic material and invertebrate cases and exuviae , and sieved them through 1 mm mesh.(2) Emerged adult Axarus and shed pupal exuviae were removed from the trap daily.(3) All specimens are exuviae , with thin and fragile carapaces and abdomens and fragmentary bodies and appendages.(4) This assemblage, perhaps representing an accumulation of molted exuviae , was apparently preserved as the result of rapid burial by carbonate muds and silts during a storm event.(5) Whether the retainment of exuviae is characteristic of the species is open to question.(6) Most scorpion fossils are thought to be exuvial .(7) Exuvial samples were collected at stations above and below organic effluent inflows ...
