| Abstract: | Stratigraphic, sedimentological, and plant macrofossil studies on proglacial lacustrine and deltaic sequences dating from the Mackinaw Interstadial on the north shore of Lake Erie, Canada, indicate long-distance transport, selective sorting and reworking of the plant fossils. Transport, sorting, and reworking may make detailed paleoclimatic indices irrelevant and may account for incongruent phytogeographic indicators in the fossil assemblage. Details of the stratigraphic and sedimentological setting of the study site and the state of preservation of the fossils should be considered more carefully as aids to the interpretation of macrofossil assemblages. |
