“A Pliocene age for the Siesta palaeosol and Nothofagus fossils has been inferred from diatom and palynological biostratigraphy.”

“The richest sources of diatom fossils are deposits of their skeletons known as diatomite, or diatomaceous earth.”

“The planktonic centric diatom Actinocyclus nonnanhi was the primary vector of tracer nitrogen to benthic and water-column organisms.”

“By this time, both groups were abundant and diversified globally, so much so that diatomite is a common marine sediment of the Miocene.”

“The richest sources of diatom fossils are deposits of their skeletons known as diatomite, or diatomaceous earth.”

“Restructuring of production in the coating kaolin and diatomite for filtration activities contributed as announced.”

“This lower interval has already been analysed for pollen, diatoms, ostracods, and gastropods.”

“Among the diatoms, there was a greater loss of pennate than centric diatoms.”

“In general, diatoms and chlorophytes had much higher biovolume than cyanobacteria and chrysophytes.”
