Characterization of the morphological types of phytoliths present in Butia paraguayensis (Barb. Rodr.) L. H. Bailey (Arecaceae)
Keywords:
cerrado, stable carbon isotope, biogenic opalAbstract
Phytoliths can be considered the most durable terrestrial fossil records, constituting an important proxy indicator for paleoenvironmental and archeological studies. This study shows the Butia paraguayensis (Barb. Rodr.) L. H. Bailey (Arecaceae) phytoliths forms, typical specie from cerrado vegetation (Brazilian savanna), considered endangered, as well as its isotopic signal (δ13C). “Globular echinate” forms were predominants. The δ13C results was of -29.1 ‰, characterizing the plant as a C3 type.
