Abstract

Three European lower Eocene localities comprising sediments from the Paleocene-Eocene Temperature Maximum (PETM, St Pankraz, Austria and Brixton, England) and the Early Eocene Climate Optimum (EECO, Krappfeld, Austria) have been investigated palynologically with light microscopy and scanning electron microscopy. The pollen taxa systematically investigated here have been affiliated to the following families and genera: Vitaceae gen. indet. and Parthenocissus, Euphorbiaceae s.s. (two “Bernardieae clade” types, Cephalocroton), Phyllanthaceae (two Flueggea types, Bischofia), one taxon of Euphobiaceae/Phyllanthaceae fam. indet., Fabaceae (“Millettioid clade” type), Anacardiaceae (two Anacardium types, Gluta, and Lannea), Araliaceae (A. gen. indet., two Aralia types, Panax, and Hydrocotyle) and one Apiaceae gen. indet. Further, we present here the earliest known occurrences of pollen of “Bernardieae clade” type, Cephalocroton, unknown Euphorbiaceae/Phyllanthaceae taxon, Flueggea, Bischofia, “Millettioid clade” type, Anacardium, Gluta, Aralia and Panax types in the fossil record.
