Phytoliths from the Southwest Pacific, Site 591 [PDF]
, 1985 Phytoliths are described from deep sea sediments at Site 591 in the southwestern Pacific. Their regional distribution is related to the arid and semiarid regions of Australia, from where they were blown by westerly winds into the Tasman Sea area.

Nuevo sistema de análisis descriptivo para fitolitos de sílice [PDF]
, 1995 El objetivo de este trabajo es el de proponer un nuevo sistema de análisis descriptivo de fitolitos de sílice. Anteriormente se habían realizado otros sistemas de análisis descriptivos para este tipo de fitolitos, especialmente en Estados Unidos.
