... expression of the north-bank stratotype. After removing weathered surfaces, we collected 62 samples (seven bentonites) from 2-cm-thick layers through 25.5 m of the Upper Hartfell Shale and the Birkhill Shale. We collected 10 further samples at the stratotype itself (55°25′46.799″N, 3°16′16.977″W) to fill a 2...

.... The types of C. miserabilis (see synonomy) come from the late Ordovician Upper Hartfell Shale. I do not agree with Williams (1987 , p. 80) that the Silurian forms have more glyptograptid thecae; when well preserved in three dimensions, they are clearly climacograptid. Nevertheless, the Ordovician forms...
