| Abstract | The principal stratigraphical data for late Ordovician and early Silurian acritarchs are reviewed; at present they do not justify any formal zonation on a broad geographic scale. The systemic basal boundary stratotype at Dob's Linn, southern Scotland, has not yielded index acritarchs. A preliminary selection of taxa from correlative strata on Anticosti Island, Quebec, eastern Canada, indicates that the area has the most continuous palynological record from at least the Ashgill to the late Llandovery, with the best potential for establishing detailed acritarch systematics and interregional correlation. |
