Rugosa of the upper Martin Formation limestones, northern Arizona (Devonian of the United States)

Where: Arizona (35.0° N, 112.5° W: paleocoordinates 25.4° S, 56.4° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Martin Formation, Late/Upper Frasnian (379.5 - 376.1 Ma)

• "The Martin fauna as a whole clearly requires extensive study and its age is difficult to assess because of the lack of published biostratigraphic data. Its general similarity to the Cerro Gordo-Sly Gap assemblage suggests provisional correlation with those late Frasnian faunas."

• formation-level stratigraphic resolution

Environment/lithology: marine; limestone

• "limestones of the upper Martin Formation"

Preservation: replaced with silica
