Also known as Is-DF-25-48
Where: Japan (24.5° N, 124.3° E: paleocoordinates 28.9° N, 121.3° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Miyara Formation, Middle Eocene (47.8 - 37.7 Ma)
• Conglomerate bed in bedded volcanics. The Miyara Formation rests on the eerosional surface of an intensely folded Paleozoic formation, and is overlain by the Miocene Yaeyama coal-bearing group. Foraminifera support an upper Eocene age, while molluscs confirm a middle Miocene age
• bed-level stratigraphic resolution
Environment/lithology: coastal; pebbly, gray, green, argillaceous, sandy, calcareous conglomerate
Size class: macrofossils
Preservation: original aragonite, original calcite
Reposited in the USNM
Collection methods: quarrying,
• Collected by D.E. Flint (1948). Reposited in the USGS of USNM collections
