Interval	Carnian
Lat/Long	33.4742,133.207
Co-ordinates derived from	stated in text
Location	Tsuno locality
Mindat.org Region (for given coordinates)	Sakawa, Takaoka District, Kochi Prefecture, Japan
Geographic Scale	outcrop
Straigraphic Comments	Ladinian?Carnian
Lithology Description	reef limestone blocks
Lithology	"reef rocks"
Environment	reef, buildup or bioherm
Geology Comments	The outcrop is situated in a small riverbed, which was dry in March 2012, 2\r\nkm north of the town of Tsuno (Tsuno district, Kochi prefecture). Reefal limestone blocks of tens of centimeters to few meters are embedded in green volcaniclastic and sparry calcite matrix. All of the collected blocks correspond to coral-sponge boundstone with minor amounts of microproblematica and algae. The preservation is good despite minor silicification. The taxonomic diversity is high (25 species were determine
