Although chrysophyte stomatocysts have a fossil record that likely extends to the lower Cretaceous, to date neither scales nor bristles of the scaled chrysophyte genera older than Holocene have been reported. This leaves the origin of this important group of freshwater algae a mystery. We discovered abundant and diverse scaled chrysophyte microfossils in ca. 47 Ma sediments (Middle Eocene, Lute...

By measuring the fluorescence spectra of pearls from various species of mother oysters, a distinction has already become possible as to whether the pearls are from Pinctada fucata, Pinctada maxima, Pteria penguin or Pinctada margaritifera. In this study, the fluorescence of pearls from freshwater bivalves was measured. The results have made it possible to distinguish freshwater pearls from the ...
