base notes	EARLIEST NANNOFOSSILS = Calcispheres, probably calcareous dinoflagellates, found in Southern Alps in Lower Carnian. Orthopithonella misurinae and Obliquipithonella prasina (calcispheres), Carnicalyxia tabellata and Cassianospica curvata (nannoliths, Incertae sedis). Appear same time as organic-walled dinocysts in geologic record. Arbitrarily assigned as mid-Early Carnian.
