Devils Gate sample 16 (Devonian of the United States)

Where: Nevada (39.6° N, 116.1° E: paleocoordinates 17.7° S, 81.9° E)

When: triangularis conodont zone, Devils Gate Limestone Formation, Early/Lower Famennian (376.1 - 370.6 Ma)

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, argillaceous limestone

• Famennian from the chaotic bed is characterizad by the choatic arrangement of large and small rounded to jagged blocks of shallow water carbonate rocks, and its emplacement is supposed to be due to a tsunami generated by the breakup of carbonate platform
• the 10 m of shales, calcareous mudstones and argillaceous limestones containing large flows of carbonate-rich silstones overlapping the FFB at Devisl Gate deposited rapidly

Size classes: mesofossils, microfossils

Collection methods: chemical
