A new, stratigraphically significant Torquigraptus species (Silurian graptolite) from the Southern Uplands Terrane

Research output: Contribution to journalArticlepeer-review

The helically coiled Torquigraptus linterni sp. nov. has a biostratigraphical range restricted to the sedgwickii and halli graptolite biozones of the upper Aeronian. In southern Scotland it occurs in the Moffat Shale Group (Birkhill Shale Formation) at the western end of the Ettrick Valley and at Dob’s Linn, and is also known from a mudstone interbed in turbidite sandstones to the north of the Megget Dam. Its associates include Torquigraptus magnificus (Přibyl & Münch), recorded for the first time in Scotland. Together, these two Torquigraptus species provide additional useful tools for correlation of lithostratigraphy in the central part of the Southern Uplands.
