Mount Irish bioherm, Northern Pahranagat Range, Lincoln Co. Nevada (Devonian of the United States)

Where: Lincoln County, Nevada (37.4° N, 115.4° W: paleocoordinates 21.7° S, 55.7° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Guilmette Formation, Frasnian (382.7 - 372.2 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; dolomitic, shelly/skeletal, black, gray reef rocks and dolomite

• in the study area, there are beds of typical guilmette overlain by a limestone breccia and a bioherm facies; the guilmette is described as interbedded dolomites and black mudstone to wackestone; the bioherm facies is sometimes described as a calcilutite in the measured section descriptions

Collection methods: chemical, peel or thin section,

• the author made collections at 16 measured sections at various horizons--this is a composite list from those 16 sections

Purpose of describing collection: paleoecologic analysis

Taxonomic list

• this list is based on all fauna listed by the author in the text of the thesis; measured sections offer sporadic faunal information and often only list one taxa from a particular horizon; where available, taxa are listed with the number of the measured section at which there was a positive idenification; gastropods and echinoderms are not identified to genus or species levels
