Word History

Etymology

phyto- + -lith, probably after New Latin Phytolitharia or German Phytolitharien, a loosely defined taxonomic division covering siliceous vegetable remains

Note: The taxon Phytolitharia/Phytolitharien was introduced by the German microbiologist Christian Gottfried Ehrenberg (1795-1876), perhaps first in a series of reports in Bericht über die zur Bekanntmachung geeigneten Verhandlungen der Königlichen Preussischen Akademie der Wissenschaften zu Berlin, aus dem Jahre 1843. Ehrenberg divided the microscopic organisms he found in marine estuary mud into three groups: "siliceous shelled Polygastrica," "calcareous-shelled Polythalmia," and "siliceous vegetable remains, Phytolitharia" (see C.G. Ehrenberg, "On the muddy deposits at the Mouths and Deltas of various rivers in northern Europe, and the infusorial Animalcules found in those deposits," Quarterly Journal of the Geological Society of London, vol. 1 [1845], p. 252).
