Glencartholm revisited: describing for the first time Stan Wood's discovery and excavation of Mumbie Quarry, adjacent to the important Palaeozoic fossil site of Glencartholm

Published online by Cambridge University Press:  03 August 2018

Abstract

Glencartholm in Dumfries and Galloway, Southern Scotland, is one of the most important Palaeozoic fossil fish sites in the world, with a fauna containing more than 30 species. Originally discovered in the bank of the River Esk in 1879, further collecting in the 1930s removed all the accessible fossiliferous strata. These strata were not known to occur elsewhere and despite the site's international importance, details of the section including the fossil bearing beds have not been described. An excavation of a new exposure at Mumbie, 50 metres east of the original site, was undertaken by Stan Wood in the 1990s. Sediments were logged over an 18-metre section. Three separate fish beds were identified and more than 200 specimens of ray-finned fish collected, including one possible new species. Differences in scale colour enables fishes from the different horizons to be distinguished. This should allow material collected previously to be more accurately assigned and assist palaeoecological analysis of the site. In addition to ray-finned fish, cartilaginous fishes were collected together with plants, bivalves, crustaceans, scorpions and horseshoe crabs which have not previously been reported from Glencartholm.
