Pollen morphotype edmundi and its significance for palaeoclimate reconstructions of the Neogene

Słodkowska B., Ziembińska-Tworzydło M.

Geological Quarterly

2017

Vol. 61, No. 2

267--275

Pollen analysis has revealed the presence of the edmundi morphotype in the Paleogene and Neogene sediments of Central Europe. Its species, characterized by different morphologies, are mainly assigned to two families of extant plants – the Araliaceae and the Mastixiaceae – and compared to pollen of some genera (Diplopanax and Mastixia from the Mastixiaceae, and Aralia, Fatsia and Schefflera from the Araliaceae). The most significant genus for palaeoclimate reconstructions is the extant Diplopanax, whose seeds, similarly as the seeds of other representatives of the Mastixiaceae, appear in the warm phases of the Neogene. The type species of Edmundipollis (E. edmundi) has been compared to Diplopanax pollen. Based on similarities with extant plants, the CA (Coexistence Approach) was determined. The results indicate a very warm and humid subtropical climate (Cfa–Cwa) according to the Köppen classification.
