Also known as Is-DF-23-55
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)
• About 8 ft above D360 and near the top of the conglomerate. 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 H.L. (1955). Reposited in the USGS of USNM collections
