Colonial Tetracoral Community Loc.523, Early Permian Nevada and Utah (Permian of the United States)

Where: Nevada and Utah (40.7° N, 114.1° W: paleocoordinates 14.6° N, 34.8° W)

• coordinate based on political unit

When: Permian (298.9 - 251.9 Ma)

Environment/lithology: packstone and grainstone

• At some of the sites, the coral heads are overturned, and at others they are aligned parallel to each other. this suggests periodic high-energy events. The prescence of common corals and echinoderms indicates normal salinity conditions.
• The enclosing rock almost always consists of packstone or grainstone, and packstone is slightly more common than grainstone.

Size class: macrofossils

Collection methods: peel or thin section

• The numbers in the list refer to a scale of relative abundance: (1) rare, (2)few, (3)uncommon, (4) common, (5)abundant.
