The mid-Palaeozoic biotic crisis: setting the trajectory of tetrapod evolution. Northern England, Scottish Borders and Nova Scotia.

The data set consists of rock samples collected from Burnmouth, a core drilled at Norham, from Crumble Edge, Willie's Hole and Nova Scotia from 2012-2016; milled material is included. There is an Excel spreadsheet of sample numbers with location, sample height on log, lithology and fossil content. Scans of field logs from Burnmouth, Crumble Edge, Edington Mill, Pease Bay (UK) and locations in Nova Scotia, and overview drawn-up logs from Burnmouth, Norham, Crumble Edge and Willie's Hole are included. Scans of thin section scans are also included. There is a spreadsheet containing geochemistry data – sample numbers with lithology and %C, %S, d13C. These data were used to interpret the environment in which early tetrapods have been found in the early Carboniferous.
