栃木県塩原層群産（更新世）のコケ植物化石について

Eleven bryophyte fossils from the Pleistocene of the Shiobara Group, Tochigi Prefecture, were studied using a stereo microscope. Based on the detailed morphological observations, eight moss species and three liverwort species were identified. Mosses include Plagiomnium maximoviczii（Lindb.） T.J.Kop., a species of Calliergon, a species of Amblystegiaceae, a species of Polytrichaceae, a species of Dicranaceae, and three species of Hypnobryales. Liverworts include Odontoschisma fluitans（Nees） L.Söderstr. & Vá㶡a, a species of Jungermanniales, and a species of Marchantiales. It is interesting to find the inclusion of the species that grow around wet habitats such as P. maximoviczii, a species of Calliergon, a species of Amblystegiaceae and O. fluitans. We consider that this reflects the bryoflora of the lakeside of Pleistocene Shiobara Lake.
