Epiphyllous fungi from the Oligocene shallowmarine deposits of the Krabbedalen Formation, Kap Brewster, central East Greenland

Abstract

ABSTRACT Fructifications of epiphyllous fungi were encountered during palynological investigation of the Lower Oligocene shallow-marine deposits of the Krabbedalen Formation at the Savoia Halvø, Kap Brewster, central East Greenland. Six fossil taxa from the family Microthyriaceae (Phragmothyrites kangukensis Kalgutkar, Phragmothyrites sp., Plochmopeltinites sp., Trichothyrites cf. ostiolatus (Cookson) Kalgutkar & Jansonius, Trichothyrites sp. 1, and Trichothyrites sp. 2) and one incertae sedis fungal remain are reported. Fungal remains from the Krabbedalen Formation represent the youngest, Oligocene occurrence of the epiphyllous fungi in the Palaeogene of the Arctic. The presence of epiphyllous, microthyriaceous fungi in low quantities and in low taxonomical diversity points to a humid and not necessarily warm climate, which is corroborated by data obtained from the analysis of microscopic plant remains.
