Lebanon (Ordovician of the United States)

Where: Tennessee (35.5° N, 86.5° W: paleocoordinates 28.1° S, 66.4° W)

• basin-level geographic resolution

When: Lebanon Limestone Formation, Blackriveran (457.3 - 449.6 Ma)

• formation-level stratigraphic resolution

Environment/lithology: burrowed, shelly/skeletal packstone and grainstone

• interbedded very thin to medium bedded calcisiltites, packstones, grainstones, and calcareous mudstones. calcisiltites: peloidal, commonly with planar lamination, hummocky cross-lamination, tool marks, trace fossils. skeletal packstones commonly fining upward, with erosional bases. grainstones commonly echinodermal and intraclastic. mudstones typically dolomitic and burrowed.

Size classes: macrofossils, mesofossils

Preservation: original calcite, replaced with calcite

Reposited in the USNM
