Also known as USGS F-265
Where: Ryukyu, Japan (24.5° N, 124.2° E: paleocoordinates 24.4° N, 124.2° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Ryukyu Limestone Formation (Sakishima Group), Late/Upper Pleistocene (0.1 - 0.0 Ma)
• The Ryukyu Limestone unconformably overlies rocks of the Ishigaki Group, the Miyara Formation, the Nosoko Formation, and the Omoto Granite. Two principal lithologies are present - a stratified sandy limestone, and a massive coralliferous limestone. Conglomeratic limestone is common at th base of the formation
• bed-level stratigraphic resolution
Environment/lithology: poorly lithified, brown, yellow, sandy, calcareous limestone and lithified, fine-grained, shelly/skeletal, calcareous limestone
Size class: macrofossils
Preservation: mold/impression
Reposited in the USNM
Collection methods: quarrying,
• Probably reposited in USGS and USNM collections
