Other records from Pennsylvania were published by DeWindt (1974), who described purported acanthodian scales (actually thelodont scales) from upper Silurian
beds of the Bloomsburg Formation, central Pennsylvania, and Giffin (1979), who published a full description of the thelodont scales from the same beds; her material is currently being re-assessed.
The thickness of the Upper Silurian

During drilling, the company found various gas shows in the middle and upper Silurian
provide a detailed study of enigmatic fossils in Upper Silurian
sequences of Bolivia and conclude that they indicate high productivity at high paleolatitudes in Late Silurian epicontinental seas.
Although much like the anomalous breccia, the Upper Silurian
Greenfield Dolomite and Tymochtee Formation are noticeably devoid of macrofossils (Swinford 1985); bedding is well developed in the Greenfield and Tymochtee, but not the breccia.
