... of a copper sulfide mineral found in association with Marrella were interpreted as evidence that the animal's blood contained the Cu-bearing protein hemocyanin. Copper minerals in shales in general, and in the Burgess Shale in particular, however, may have a complex geologic history. Using microscopy and SEM...

.... Since modern-day arthropods generally utilize Cu-containing hemocyanin for oxygen transport, it is hypothesized that hemocyanin was the biogenic source of the observed Cu. This is the first chemical evidence for blood composition in the invertebrate fossil record. These observations reinforce...

... apparently concentrate only a few trace elements; but, significantly, copper and vanadium are among these elements. Hemocyanin, a copper porphyrin, serves as a respiratory pigment in some of the lower animals such as the crustaceans. Significant amounts of vanadium are concentrated from sea water...

... of a number of enzymes. For example, hemocyanin is a complex copper protein analogous to hemoglobin and is involved in the oxidative transport of di-oxygen in the blood stream of some mollusks and arthropods. Cytochrom oxidase is a Fe-Cu protein (enzyme) with three copper sites and is found pinned...

... metal found in ores, is the principal metal in bronze and brass. It is a reddish metal with a density of 8920 kg m −3 . All of copper’s compounds tend to be brightly colored: for example, copper in hemocyanin imparts a blue color to blood of mollusks and crustaceans. Copper has three oxidation states...
