Biostratigraphic and Lithostratigraphic Analysis of the Hindsville Limestone (Mississippian) in Northwestern Arkansas [PDF]

open access: yes, 1974
Several lithofacies can be recognized within the Hindsville Limestone (Mississippian) in its type area near Hindsville, Madison County, Arkansas. Lithofacies are based on petrographic analysis of matrix and constituent particles, particularly ooliths and

Conodont dating of some Telychian (Silurian) sections in Estonia [PDF]

open access: yes, 2008
Several Telychian–Sheinwoodian strata exposed in Estonia are precisely dated using conodont biostratigraphy. The beds in the Valgu-1 section correspond to the uppermost Distomodus staurognathoides and Pterospathodus eopennatus ssp. n. 1 zones.
