Seagrass fossils from the lower Miocene Morozaki Group in Aichi Prefecture, central Japan
Abstract
Two new seagrass fossils are reported from the upper lower Miocene Morozaki Group (18.0–17.6 Ma) of central Japan: Thalassites morozakiensis T. Yamada, sp. nov., and Maresurculus aichiensis T. Yamada, gen. et sp. nov. The former bears strap-shaped, eligulate leaves enclosed within a fibrous sheath, suggesting an affinity with the extant subfamily Hydrilloideae (Hydrocharitaceae). The latter is characterized by ligulate leaves shed without leaving a sheath on the stem, indicating a relationship to extant genera of Cymodoceaceae, such as Amphibolis and Thalassodendron. These fossils represent….
