VU-12 Vulcan Quarry, Wayne Fm., Wenlock conodonts (Silurian to of the United States)

Where: Hardin County, Tennessee (35.2° N, 88.2° W: paleocoordinates 30.4° S, 55.6° W)

• coordinate estimated from map

When: Lego Member (Wayne Formation), Wenlock to Wenlock (433.4 - 423.0 Ma)

Environment/lithology: open shallow subtidal; lithified packstone and lithified wackestone

• Skeletal packstones dominate this facies, but wackestones are also common. Skeletal grains are more abundant than in Facies I and the quantity of lime mud is correspondingly less. Remains of echinoderms increase significantly and bryozoan and trilobite detritus increase slightly from Facies I. Ostracodes and molluscan remains are less common. Skeletal preservation is good, but more larger grains are broken than in Facies I and some are abraded. The number of unidentified skeletal grains is less than in Facies I, largely due to the scarcity of the slender unidentifiable grains common in that facies. Some sorting of skeletal grains has occurred, but this is not common.

Size class: microfossils

Preservation: original phosphate
